it is a code in MATLAB for calculation of bit error ratio vs signal to noise ratio , for multiuser code division multiple access .. usually in any communication system calculation of BER is very important to know the performance of system .. so in th

This Matlab Code models a Rayleigh fading channel using a modified Jakes channel model.
A modified Jakes model chooses slightly different spacings for the scatterers and scales their waveforms using Walsh–Hadamard sequences to ensure zero cross-co

It includes coding for walsh code encoding in matlab.The Walsh functions can be generated (or computed) by many methods. We can construct the Walsh functions by:
• Using Hadamard matrices
• Exploiting the symmetry properties of Walsh

It does walsh decoding in matlab.For w5 i.e. 100
Walsh code T = 01100110
For bit a3 at T/2
So a3=1
Similarly same things is do for T/4,T/8……..
Continuing the same steps we get w5=100
