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 interference. Also, we analyze the BER performance of proposed system through simulation using C-language and Matlab. In fading and ISI channel, the simple recycling equalizer gives 7 dB gains in Eb/No comparing with no equalizer case.
