berrayleighphaseerror.m

这是一个关于完成QAM调制的Matlab示例程序

function [ber] = BerRayleighPhaseError(gammaB,phase)
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% This is just a utility function to compute the expected BER
% of a signal in Rayleigh fading with phase error in the receiver
%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

ber = .25*(2-(cos(2*phase)*sqrt(gammaB)*(sqrt(1/(1-sin(2*phase)+((cos(2*phase).^2)*gammaB)))+...
    sqrt(1/(1+sin(2*phase)+((cos(2*phase).^2)*gammaB))))));

return
