| Abstract: | A new multi-stream differential unitary space-time-frequency code scheme is proposed which is used in the MIMO-OFDM system and based on cyclic delay diversity.The scheme uses the differential and unitary matrix together with the advantage of the orthogonal space-time code,and thus the bit error rate performance of the whole MIMO-OFDM system is improved greatly without channel estimation. |
