MATLAB BPSK Demodulation Implementation

function output_frame = demodulation1(input_modu, index) % demodulation for IEEE802.11a % Input: input_modu, complex values representing constellation points % index % Output: output_frame, output bit stream (data unit is one bit) % In this version, increase the quantilization levels into 8. % note: MATLAB index starts from 1 Q_length=length(input_modu); QAM_input_I = real(input_modu); QAM_input_Q = imag(input_modu); output_frame = zeros(1,length(input
