Abstract :
In this paper, we propose a new improved TH precoding algorithm, which intends to solve the problem of high bit error rate (BER) from traditional THP algorithm when the channel is in bad condition, and compare the performance with different classic ZF-THP and MMSE-THP. Also the conclusion is verified by emulation. Based on the Precoding module algebra, we proposed the Reduce Grid Algorithm which has high efficiency, and pre-coding scheme based on the Reduce grid algorithm, which can be used in non-ideal MIMO model.
