This book was released on 2023-09-18 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two important topics of information theory are compression and error correction codes. These are known as source and channel coding techniques. Source coding helps to compress the data and improves bandwidth utilization. Channel coding adds redundancy to make data more reliable. Error correction coding is the means whereby errors can be detected and corrected using redundant bits. Error correction codes are of two types, forward error correction and automatic repeat request. Mobile communications have seminal importance in present telecommunication systems. Wireless transmission is used to convey data between user end and base stations. The communication errors are caused due to noise, interference and poor signal strength. Mobile communication system presently uses Turbo channel code to detect and correct errors. Presently, there is a high demand for mobile services and its applications. Usage of smart phones has increased largely and that is demanding higher data rate and large network capacity to meet intensive service requirements. This demands large bandwidth which is limited and valuable resource. The requirements to support real time voice communication in mobile system with different available standards are Bit Error Rate and Latency. Further, the capacity to scale up in channels, coverage area and seamless integration of Polar-code based systems with minimum design efforts are thrust areas. Shannon, pioneer of information theory expressed in year 1948, that data can be transmitted reliably through the channel at maximal possible rate. The prime goal of coding theory since 1948 till date is to design a practical error correcting coding scheme that can be implemented in real time communication. The work focuses on developing such practical Polarcode based system. Polar-codes was introduced by Erdal Arikan in 2009. The application considered in present work is voice and data for mobile communication. Polar-code is used along with spectrum efficient MPSK modulation techniques in the presence of additive white Gaussian noise. The main objective is to increase the number of users with same bandwidth. Simulation is carried out to optimize the Power, Bandwidth and Latency parameters for acceptable Bit Error Rate of 10-4. Taguchi and Response Surface Methodology techniques are used for performance optimization using Polar-code. A single transmission time interval mechanism is used for circuit switching technique. Based on this, a Polar-code based OFDM system is simulated with 12 subcarriers. It is observed that the SNR required to achieve BER of 10-4 is 5.84 dB, 12.62 dB, 18.84 dB for QPSK, 8 PSK and 16 PSK modulations respectively. To extend the applicability to packet switching technique with BER of 10-4, three transmission time intervals mechanism is simulated with Polar-code OFDM system. The SNR of 2.84 dB, 9.62 dB, 15.84 dB is obtained for QPSK, 8 PSK and 16 PSK modulations respectively. The experimentation has been carried on a frame of length 528 bits with QPSK and 16 PSK OFDM system. Here Polar-code is used for bit error correction and CRC of 8-bit, for frame error detection. The frame error rate considered is of 10-3 and 10-4. This system provides link utilization of 32.43% and 32.46 % for data rate of 100 Mbps. With 10 Mbps data rate, link utilization achieved is 75% and 83.32 %.

Available in PDF, EPUB and Kindle. Book excerpt: Treats joint source and channel decoding in an integrated way Gives a clear description of the problems in the field together with the mathematical tools for their solution Contains many detailed examples useful for practical applications of the theory to video broadcasting over mobile and wireless networks Traditionally, cross-layer and joint source-channel coding were seen as incompatible with classically structured networks but recent advances in theory changed this situation. Joint source-channel decoding is now seen as a viable alternative to separate decoding of source and channel codes, if the protocol layers are taken into account. A joint source/protocol/channel approach is thus addressed in this book: all levels of the protocol stack are considered, showing how the information in each layer influences the others. This book provides the tools to show how cross-layer and joint source-channel coding and decoding are now compatible with present-day mobile and wireless networks, with a particular application to the key area of video transmission to mobiles. Typical applications are broadcasting, or point-to-point delivery of multimedia contents, which are very timely in the context of the current development of mobile services such as audio (MPEG4 AAC) or video (H263, H264) transmission using recent wireless transmission standards (DVH-H, DVB-SH, WiMAX, LTE). This cross-disciplinary book is ideal for graduate students, researchers, and more generally professionals working either in signal processing for communications or in networking applications, interested in reliable multimedia transmission. This book is also of interest to people involved in cross-layer optimization of mobile networks. Its content may provide them with other points of view on their optimization problem, enlarging the set of tools which they could use.

Download or read book Polar Codes for Data Storage and Communication Network Applications written by Karthik Nagarjuna Tunuguntla and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dissertation provides polar coding techniques for a variety of source and channel models with applications to storage and communication networks. We first provide universal polar codes for asymmetric compound channels that avoid common randomness. A staircase alignment of polar blocks is considered in the code construction. An MDS code is used in each column achieving the universality and a scrambling technique is implemented for each column helping avoid common randomness. These compound asymmetric channels are used for modelling flash-memories, such as MLCs (multi-level cell flash memories), and TLCs (three-level cell flash memories) memories. Hence the proposed universal polar codes for asymmetric channels can be used for flash memory error correction. The costly noiseless channel model was used to model a flash memory device. Each of the voltage levels to which a flash memory cell can be programmed has an associated wear cost which reflects the damage caused to the cell by repeated programming to that level. Shaping codes that minimize the average cost per channel symbol for a specified rate and shaping codes that minimize the average cost per source symbol (i.e., the total cost) have been shown to reduce cell wear and increase the lifetime of the memory. Hence, we study polar shaping codes for costly noiseless channels minimizing total cost. We also study polar shaping codes for costly noisy channels for the design of efficient codes that combine wear reduction and error correction for use in a noisy flash memory device. A novel scheme based on polar codes is proposed to compress a uniform source when a side information correlated with the source is available at the receiver while the conditional distribution of the side information given the source is symmetric and unknown to the source. An adaptation of universal polar codes with an incorporation of the linear code duality between channel coding and Slepian-Wolf coding is used in the design of those codes. Optimal rate is achieved through the proposed codes for the source model. These codes can be used in a wireless sensor network where the measurements tracked at two different nodes are correlated and the correlation may not always be fixed due to environmental changes such as weather. The nodes communicate the information sensed or measured by them to a central location. Finally, we provide a capacity-achieving polar coding strategy on a multi-level 3-receiver broadcast channel in which the second receiver is degraded (stochastically) from the first receiver for the transmission of a public message intended for all the receivers and a private message intended for the first receiver. A chaining strategy, translating the ideas of superposition coding, rate-splitting and indirect coding into polar coding, is used in the construction. The codes designed for such a channel model and setting can be used for video and audio file transfer in a client-server network where the individual clients are a computer and two mobile phones. The two mobile phone clients just support audio application where the computer supports both audio and video applications.
