complex_mul.m

alamouti結合ofdm系統下 做的仿真系統。 提供大家討論使用 不懂的再與我聯絡吧

function [I_out, Q_out] = complex_mul(I_in, Q_in, h_I, h_Q)
%% function [Iout, Qout] = complex_mul(Iin, Qin, Hi, Hq)
% Perform complex multiplication (signal constellation rotating, weighting...)
% Input:
%   I, Q: two vectors containing the I & Q of the signals before rotating
%   Hi + jHq: rotating factors
% Return: vectors I, Q of the results

I_out =  I_in*h_I - Q_in*h_Q;      
Q_out =  Q_in*h_I + I_in*h_Q;
