Hi Guys,
Im stuck with a simulation in matlab, i am trying to simulate some results i have found in this paper(paper attached), basically im having trouble defining the Rayleigh fading in equation 6 of the paper (3rd page) it basically captrues the rayleigh fading of the target signal, so far i have been trying to define is using the random function this is what i have at the moment,
rayf = sqrt(0.5)*(randn(1,2) + j*randn(1,2)); OR something like this
randn(2) * sqrt(0.5) + 0; %2d, mean 0, variance 0.5
Neither one seems to be right, the reason i did this is because it specifies that the Rayleigh fading follows a normal distribution. I have also attached my entire code but i dont know if anyone is going to be able to go through it its very messy, hopefully someone can help out.
Thanks.
