Software Listing: Rayleigh

This script simulates QPSK or 4-QAM modulation scheme in Rayleigh channel and compares it to theoretical limits. QPSK gives 3dB SNR degradation when compared to BPSK but twice as much throughput. I hope this will be helpful for students of wireless communication..

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.

CHI2RAYLTEST: Single sample Pearson Chi Square goodness-of-fit statistical test to examine a null hypothesis of Rayleigh Channel. H=CHI2RAYLTEST(X,ALPHA) performs the particular case of Pearson Chi Square test to determine whether the null hypothesis of a Rayleigh channel realization is a reasonable assumption regarding the population distribution of a complex random sample X with the desired significance level ALPHA. H indicates the result of the hypothesis test according to the MATLAB rules of conditional statements: H=1 => Do not reject the null hypothesis at significance level ALPHA. H=0 => Reject the null hypothesis at significance level ALPHA.

Dent Rayleigh model is similar to Jakes but uses Hadamard function in MATLAB to make the oscillators (somewhat) independent and thus provide results that are a little more realistic than the Jakes model. For more details, please read IEEE paper by Wu Z. from 2004 (Electronics Letters, Volume: 40, Issue: 15) that covers the statistical performance of several models, including the Dent. In this paper Wu proposes his own model which is even better than the Dent. Function Usage Example: [omega_mTau, Tk] = RayCh(2^7, 2^18, 64, 2, 900, 100) where NumAngles=2^7, Length=2^18, symbolRate=64, NumWaveforms=2, carrierFreq=900, Velocity=100 I have created this function for my own purpose, specifically for the use in my OFDM channel estimation model.
