Walsh-Hadamard codes are mutually orthognal codes,
thus when used in synchronous CDMA, the interference between users is zero.
This programm generates Walsh-Hadamard codes and also checks the orthogonality.
You can change the code length by

Matlab code to study the decorrelation and energy packing efficiency of three transform
techniques: Karhunen-Loève transform (KLT), discrete-cosine transform (DCT), and Walsh-Hadamard transform (WHT). Using a given vector of signal samples, it tra

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
