%X It is difficult to estimate channel knowledge in multiple input multiple output system which based on distributed antenna structure because the transmit signals are received asynchronously. Aiming at this matter, a differential encoding and detection scheme is proposed where channel estimation is not needed. The proposed scheme has the same spectral efficiency as V-BLAST scheme and can be applied to any number of transmit antenna and receive antenna, besides the number of receive antenna can be less than transmit antenna. The simulation results show that the BER performance is different corresponding to different channel propagation delay.
