  Abstract

For the multimedia data service, high speed data transmission is required. Bit error rates can be increased due to interference of multipath and intersymbol during data transmission through wireless channel. Therefore, in this paper, we proposed π/4-DQPSK OFDM system with equalization scheme to overcome these interference. Also, we analyze performance of proposed system through simulation. In fading and ISI channel, we obtained better gains of 7dB with equalizer than without.
