Transmit beamforming using M-QAM

Follow the link for MATLAB file of Beamforming using M-QAM modulation in Rayleigh fading channel.

You can simply change the order of modulation to simulate it for M=4,16,64,128..

Gram Schmidth Algorithm implemented in MATLAB

In digital modulation techniques a set of basis functions are chosen for a particular modulation scheme.Generally the basis functions are orthogonal to each other. Basis functions can be derived using 'Gram Schmidt orthogonalization' procedure.Once the basis function are chosen, any vector in the signal space can be represented as a linear combination of the basis functions.
Gram–Schmidt process is a method for orthonormalising a set of vectors .The Gram–Schmidt process takes a finite, linearly independent set and generates an orthogonal set.
