As one of the most important technologies, MIMO-OFDM has attracted a lot of attention. It can enormously improve the data-transmission rate and the reliability in complex environments of wireless communication without increasing the spectrum bandwidth and the transmission power. Space-time code is a way which can implement the performance of the MIMO-OFDM. Here, some work has been done according to the researches at home and abroad.
Firstly, difficulties faced by modern communication and the advantages ...
