Electronics Project:OFDM

Implementation on OFDM system in Matlab:

High data rate wireless access is demanded by many applications. Usually, more bandwidth is required for higher data rate transmission in any of the system. With promising technology and ever-increasing wireless devices, the spectrum is becoming scarcer day by day. In this case, using Orthogonal Frequency Division Multiplexing (OFDM) for spectrally efficient transmission is an alternative solution.

OFDM is a bandwidth efficient multicarrier modulation where the available spectrum is divided into subcarriers, with each subcarrier containing a low rate data stream. OFDM has gained a tremendous interest in recent years because of its robustness in the presence of severe multipath channel conditions with simple equalization, robustness against Inter-symbol Interference (ISI), multipath fading, in addition to its high spectral efficiency.

This project implements the OFDM system with different modulation techniques in Matlab. It uses Gaussian noise channel for calculating bit error rate in the OFDM transmission system.
