在直接序列扩谱（ＤＳ－ＳＳ）系统中，横向均衡器（ＴＥ）能够有效地克服多径干扰．本文在文［２］的模型基础上给出了ＴＥ的稳态解，指出系统的稳态性能由有效信号和干扰信号的相关系数决定．实际系统中相关系数是时变的，用实验方法统计得到相关系数以趋近１的概率落在［０，０．３］之间，证明相对匹配滤波器接收，ＴＥ能有效地抑制多径干扰．另外，文中还分析了其它参数对系统性能的影响．
In direct-sequence spread spectrum (DS-SS) systems, horizontal equalizers (TEs) can effectively overcome multipath interference. This paper gives the steady-state solution of TE based on the model in [2], and points out that the steady-state performance of the system is determined by the correlation coefficient between the effective signal and the interference signal. The correlation coefficient in the real system is time-varying, and the probability that the correlation coefficient approaches 1 by the experimental method falls between [0, 0.3], which proves that the relative matched filter can receive and TE can effectively suppress multipath interference . In addition, the article also analyzes the impact of other parameters on system performance.
