hello der,

I am doing my project in analysis of adaptive beamforming algorthims (LMS and NLMS) in smart antennas...am not able to get proper output,

i have done the coding i dnt know where am i going wrong...it might be because of not giving AWGN and BPSK,,,even the output for errors are wrong....
can anyone please help me out...
