Modulator

PURPOSE ^

Modulates data symbols (possibly pre-equalized).

SYNOPSIS ^

function [ s ] = Modulator( d, Para )

DESCRIPTION ^

 Modulates data symbols (possibly pre-equalized).

 function [ s ] = Modulator( d, Para, modulation )

 The function works for SISO and MIMO systems.

 Input arguments:

   d: data symbols (possibly pre-equalized). Size: matrix [2*Para.M, ~] if Para.N_T == 1,
   multidimensional array [para.N_T, 2*Para.M, ~] if Para.N_T > 1.  

   Para: structure containing the modulation parameters.

 Outputs arguments:

   s: transmitted signal. Size: matrix [Para.N_T, ~]

CROSS-REFERENCE INFORMATION ^
