This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quadrature Amplitude Modulation (QAM) has been predominant in current wireless digital communications, such as satellite and microwave radio communications. Due to diverse wireless communication applications, a digital QAM modem with diverse bit rates (R) and intermediate carry frequency (IF) is of great interest. The main objective of this thesis is to design, analyze and implement a multi-level QAM modem with programmable bit rates and programmable IF, thus not only meeting different requirements, but also dramatically reducing the complexity of the following analog Radio Frequency (RF) block. In the thesis, the digital QAM modem is built based on the fundamentals of Digital Communication Systems (DCS) and Digital Signal Processing (DSP). The underlying relationship between signal resampling and its filter impulse response is studied and analyzed. A new signed-array structure for 2's complement multiplication is introduced in order to improve the regularity and flexibility of hardware design. The modem analysis and comparisons are shown in terms of performances and structures. Hardware design techniques are developed in-depth. The modem model is coded in VHDL (VHSIC Hardware Description Language) and synthesized using Synopsys tools, and its performance is evaluated. The regular structure and portable VHDL coding of the modem can satisfy diverse applications implemented in different FPGAs or ASICs.

This book was released on 1996-12-01 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern digital communication systems are being called upon to move ever increasing amounts of information over decreasingly available bandwidth. This requires that communication systems employ bandwidth-efficient modulation schemes to conserve bandwidth while moving the information at higher data rates. A major stumbling block to using higher order modulation schemes in long haul communication is the distortion caused by high power amplifiers. These high power amplifiers are required to amplify the signal power to a level that will allow distant receivers to correctly demodulate and decode the information. The distortion caused by the high power amplifiers can render a modulation scheme unusable due to the high symbol error rates which result from the extensive skewing of the modulation scheme's signal constellation. This thesis details a predistortion technique using Volterra series approximation techniques to model the inverse of the high power amplifier's distortion characteristics. A 64 Quadrature Amplitude Modulation (64-QAM) system incorporating a predistorter is used to demonstrate the ability to achieve acceptable bit error rates. The implementation of the inverse model and the communication system is performed in MATLAB. The results show the viability of predistortion of digital data to allow the higher order modulation schemes to be incorporated into communication schemes, increasing the overall data rate while conserving bandwidth.
