Abstract

Classical space-time coding methods, such as BLAST, STTC, and STBC, are coding methods based on perfect channel state information, and are decoded by coherent detection. In order to obtain the utilization rate of high-frequency bands and the gain of spatial diversity and multiplexing. However, when the network nodes move rapidly, the periodic pilot symbol channel estimation method has a large time delay. Especially when the number of transmitting antennas is relatively large, the channel training time is highly complex, and it is difficult to meet the requirements of coding accuracy. Based on the above considerations, this paper proposes a space-time-frequency coding method based on MIMOOFDM system. Compared with space-time coding, this space-time-frequency coding method makes full use of the frequency diversity gain of the MIMO-OFDM system to improve the performance of the system.
