psk_gen.m

该系统主要使用matlab实现了stbc2*1系统的发送和接收

function [Msymb,Sset]=psk_gen(Mary,symb)
%[Msymb,Sset]=psk_gen(Mary,symb)
%Mary is order of PSK set, eg. Mary = 4 is QPSK
%symb is the index of the symbol ranging from 1:Mary.
%Msymb is the modulated output

if nargin == 1, symb = 1:Mary; end

Sset = exp(-i*2*pi/Mary*(0:Mary-1))';
Msymb = Sset(symb);
