Abstract-The effect of the companding process on QAM signals has been under investigation for the past several years. The compander, included in the PCM telephone network to improve voice performance, has an unusual affect on digital QAM data signals which are transmitted over the same channel. The quantization noise, generated by the companding process which is multiplicative (and asymmetric), degrades the detectability performance of the outermost points of the QAM constellation more than that of the inner points. The combined effect of the companding noise and the inherent white gaussian noise of the system, leads us to a re-examination of signal constellation design. In this paper we investigate the detectability performance of a number of candidates for signal constellations including, a typical rectangular QAM constellation, the same constellation with the addition of a smear-desmear operation, and two new improved QAM constellation designs with two-dimensional warpi

This a GUI based system. The GUI is invoked from the command line by typing "ui_start". The GUI is self explanatory. Tool tips are given in blue color. The cursor needs to be positioned on these for detailed explanation. The main file is "runsim.m". In these simulations the SISO option is not explicitly given. This is because the SISO result for a particular type of modulation is shown in every plot for purposes of comparison. This software has been tested on MATLAB version 6.0 and above with signal processing and communication toolbox options.

The main file in this list of programs is "vblast.m". Type "help vblast" on the command line for details.Study the coding by stepping through the program. These programs require around 5000 packets for reasonable plotting accuracy.This has been implemented for a 2x2 system. The reader can program other variations. The program has been tested on MATLAB version 6.0 and above with signal processing toolbox and communication toolbox options.

This chapter contains sample programs for determining capacity. The reader is advised to go through the coding. The file "capacity_water.m" is for measuring the waterfilling capacity. It should be made to work with a file similar to "capacity_plot_main.m". The latter file deals with all the other capacity plots given in the book in Chapter 2. All programs are verified with MATLAB versions 6.0 and above with signal processing and communications toolboxes.
