| 摘 要： | UWB信号在密集室内信道中存在严重的多径衰落.利用IEEE802.15.3a标准信道模型,研究分析了不同Rake接收对系统性能的影响,对TH-PPM-UWB系统在标准信道模型下接收端分别采用ARake、SRake和PRake接收的误码率进行了仿真比较.结果表明采用SRake易于实现且可以有效降低误码率、提高系统性能.

| Abstract: | There is serious multipath in indoor channel.Based on the Intel model approved by the IEEE 802.15.SG3a group,the effect of different Rake receivers on system performance is studied.The BER(bit error rate) performance of ARake,PRake,SRake for TH-PPM-UWB(Time-hopping pulse position modulation ultra wideband) system is simulated and compared.The result indicates that SRake receiver perform easily and can efficiently improve the performance of UWB system. |
