Abstract: An improved OFDM system is proposed: N-points-FFT is divided into n groups. The symbol is arranged according to orthogonal design theory at transmitter, and the multi-antenna can achieve the maximum signal power by appropriate combination method at receiver. The performance is improved greatly by analysis and numerical simulation.

Key words: FDM, diversity, FFT
