Research and improvement of TH precoding in MIMO system

摘要：

　　TH precoding can effectively eliminate the interference between the channels in the MIMO system,improve the reliability of the system.Compared with the linear precoding,the capacity of the system also has a considerable increase.But there are still some problems.In this paper,the traditional TH precoding is improved.The channel matrix H is decomposed by GMD.The SNR of the parallel MIMO subchannel becomes the same and the difference of each parallel MIMO subchannel performance is small.Not only this has certain advantages in the performance of BER,but also we can implement the same modulation and demodulation schemes to parallel MIMO subchannels.It reduce the complexity of processing.
