Software Listing of Author : "Krishna Sankar M"

Simple Matlab example simulating a BPSK transmission and reception in Rayleigh channel. The script performs the following (a) Generate random binary sequence of +1's and -1's. (b) Multiply the symbols with the channel and then add white Gaussian noise. (c) At the receiver, equalize (divide) the received symbols with the known channel (d) Perform hard decision decoding and count the bit errors (e) Repeat for multiple values of and plot the simulation and theoretical results. The theoretical description provided in http://www.dsplog.com/2008/08/10/ber-bpsk-rayleigh-channel/

Derives the transfer function for digital implementation of a first order RC low pass filter and plots the step and frequency response. For details, refer to the post: http://www.dsplog.com/2007/12/02/digital-i...ow-pass-filter/

Discuss the case where there a multiple (two) transmit antennas and multiple (two) receive antennas resulting in the formation of a 2x2 Multiple Input Multiple Output (MIMO) channel. We will assume that the channel is a flat fading Rayleigh multipath channel and the modulation is BPSK. The equalization scheme used is Zero Forcing. As expected, the simulated results with a 2doOCo2 MIMO system using BPSK modulation in Rayleigh channel is showing matching results as obtained in for a 1doOCo1 system for BPSK modulation in Rayleigh channel. For more theoretical description of Zero Forcing Equalization in 2x2 MIMO channel, please check http://www.dsplog.com/2008/10/24/mimo-zero-forcing/
