Listing of Communication in Scripts

In this programe a highly scattered enviroment is considered. The Capacity of a MIMO channel with nt transmit antenna and nr recieve antenna is analyzed. The power in parallel channel (after SVD decomposition) is distributed as water-filling algorithm The pdf of the matrix "lanada" ( V in SVD decomposition) elements is depicted too.
