BER performance of LBC coded OFDM in different channels

Orthogonal Frequency Division Multiplexing (OFDM) has attracted lot of attention of researchers because of its vital role of it in wireless communication technology. This paper discusses the Bit Error Rate (BER) performance of OFDM system using Differential Phase Shift Keying (DPSK) under various channel conditions. It is seen that coding improves BER performance of OFDM and hence in this work Linear Block coding (LBC) is used for improvement purpose. The reason of selecting differential detection modulation scheme is its receiver structure is simple. The simulation is carried out in MATLAB simulink.
