摘 要: 根据RAKE接收机的原理,采用分集接收的方法有效地降低了多径衰落的影响。首先对一种多径分集技术(RAKE接收机的原理)进行详细描述,分析其对多径衰落的补偿有效性,又提出一种基于神经网络的RAKE接收机模型,并进行仿真实验。结果表明:这种RAKE接收机能够很好地抑制煤矿井下多径干扰,改善链路的性能,具有更好的误码性能。
关 键 词: 通信传输技术;多径干扰;RAKE接收机;神经网络

Abstract: According to the principle of RAKE receiver, this paper used the method of diversity reception to effectively reduce the impact of multipath fading. It first described the principle of a multipath diversity technology, namely RAKE receiver in detail, then analyzed its compensation effectiveness for the multipath fading. It also proposed a model of RAKE receiver based on neural network, and made a simulation experiment. The results show that the RAKE receiver can effectively inhibit the multipath interference in underground coal mine and improve the link performance. This RAKE receiver has better BER performance.
Key words: communication transmission technology; multipath interference; RAKE receiver; neural network
