摘　　要：对于超宽带(UWB)无线通信技术来说,无线信道的特征直接决定了能否实现高速数据传输、低功耗、低复杂度的无线通信系统。基于多径传播、路径损耗、信道响应等参数,对IEEE 802.15.3a UWB技术的信道模型进行建模,并将RS编码和BPSK调制技术与UWB无线信道模型相结合,对4种环境下的传播情况进行仿真研究。结果表明,信道仿真的结论与实测数据结论一致性较好,所建模型能够准确反映和评估UWB无线通信的信道特征。For ultra-wideband wireless communication technology,the characteristics of its wireless channel directly determine whether the wireless communication system can achieve high-speed data transmission,low power consumption and low complexity.This article models the channel model of IEEE 802.15.3a ultra-wideband technology based on parameters such as multipath propagation,path loss,and channel response.RS encoding and BPSK modulation techniques are combined with ultra-wideband wireless channel models to study and simulate the propagation situation in four different environments.The results indicate that the conclusions of channel simulation are consistent with the measured data,and the constructed model can accurately reflect and evaluate the channel characteristics of ultrawideband wireless communication.
