给出了高速率室内UWB系统基于积分窗口能量收集算法的理论分析框架。首先得到等效信号接收模型,再使用MLSE均衡消除ISI。从等效接收信号模型可以看出,ISI干扰呈非对称的特点,其主要原因在于积分窗口的长度是信道扩展延迟的一部分,这样ISI之前的干扰比特个数大于之后的比特干扰个数。使用Viterbi算法进行MLSE,仿真结果表明,MLSE均衡基本可以消除ISI影响,达到接近无ISI的性能。 The theoretical analysis framework based on integral window energy harvesting algorithm for high rate indoor UWB system is given. First get the equivalent signal reception model, and then use the MLSE equalizer to eliminate ISI. It can be seen from the equivalent received signal model that the ISI interference is asymmetric. The main reason is that the length of the integration window is a part of the channel extension delay, so that the number of ISB interference bits is greater than the number of subsequent bit interferences. Viterbi algorithm is used to carry out MLSE. The simulation results show that MLSE equalization can basically eliminate the influence of ISI and achieve the performance close to that of ISI.
