自适应滤波原理_西蒙.赫金_Matlab_源代码 希望能够对学习自适应滤波技术的朋友有所帮助

function [Msymb,Sset]=psk_gen(Mary,symb)
%
%Routine used to generate an unnormalizd psk symbol set
%mary is the Mary of the PSK set, eg Mary = 4 for QPSK set
%symb is the index of the symbol, ranging from 1:Mary
%Msymb is the modulated output

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

bits = log2(Mary);
Sset = exp(-i*2*pi/Mary*(0:Mary-1))';
Msymb = Sset(symb);
