Nonlinear Pre-processe Technology in Wireless Communication Downlink
Xianzhong Xie · Communications technology · 2007
This paper first introduces the classic Tomlinson-Harashima Precoding(THP),then makes analysis respectively on the trellis preceding and nonlinear transmit zero-forcing based on THP,including their features,and point out that the nonlinear pre-processing technology is the tradeoff of performance and complexity and has potentialities for the downlinks. Finally a new pre-processing technology is proposed,which also has good performance.
