OFDMA basics

This section of MATLAB source code covers OFDMA transmitter and OFDMA receiver MATLAB code.

Following download link provides the generic OFDMA matlab transmitter code. Unlike OFDM where in data from mapper is mapped on to all the used sucarriers of the entire FFT, In OFDMA subcarriers of the entire FFT is divided into subchannels and few of the subchannels are allocated to one mobile subscriber. This page provides MATLAB code for OFDMA as per IEEE 802.16e standard. This works only for 512 point FFT.
