| 摘 要： | 首先介绍了经典的汤姆林森预编码技术,然后分别介绍了在其基础上发展起来的两种预处理技术——网格预编码和传输非线性迫零,并分析了其特点,指出非线性的预处理技术是性能和复杂度的折中,是很具潜力的一种下行链路技术。最后文中给出了一种新的预处理技术,同样具有较好的性能。

| Abstract: | 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. |
