| 摘 要： | 本文介绍了一种适合于网格编码调制（ＴＣＭ）系统的均衡方法。这种方法基于预均衡结构，回避了网格译码不能提供判决反馈均衡（ＤＦＥ）所需的可靠的零时延判决的问题。本文从迫零判决反馈均衡器出发，利用网络编码市制的格形（Ｌａｔｔｉｃｅ）分割原理，推导出这种均衡器的结构。这种均衡器不但能够对带限符号间干扰信道进行均衡，而且当传输速度。较高时时，所采用的预均衡结构不影响预均衡器的输入序列的分布特性。因而可以支持

| Abstract: | In this paper,an equalizer based on pre-equaliz ation for trellis coded modulation(TCM) system is presented The problem that th e trellis decoder can no t provide reliable zero-delay decision for the decision-feedback equalizer(DFE) is avoided The new structure is derived from the zero-forcing decision-feedb ac k equalizer(ZF-DFE) using the lattice partition theory of the TCM The proposed method can equalize the band limited ISI channel and (at high rates) does not im pact the distribution of the input of the pre-equalizer Simulation results con firm the efficiency of this method for TCM system |
