SeparatePreambleData

PURPOSE ^

Separates preamble and data symbols.

SYNOPSIS ^

function [ z_preamble,z_data ] = SeparatePreambleData(z,Para)

DESCRIPTION ^

 Separates preamble and data symbols.

 function [ d ] = MergePreambleData(d_preamble,d_data,Para)

 The function works for SISO and MIMO systems.

 Input arguments:

   d_preamble: symbols in the preamble

   d_data: data symbols

   Para: structure containing the modulation parameters.

 Outputs arguments:

   d: frame constaining preamble and data symbols

CROSS-REFERENCE INFORMATION ^
