考虑了采用二进制块编码脉冲位置调制（PPM）和多径信道中次优接收器的单用户超宽带（UWB）通信系统的性能。所检查的接收机包括具有各种分集组合方案的 RAKE 接收机和与传输参考 (TR) 信令结合使用的自相关接收机。提供了一个通用框架，用于推导这些接收机在受加性高斯白噪声 (AWGN) 破坏的多径信道中的性能。通过采用之前对室内 UWB 信道的测量，我们获得了几种情况的数值结果，这些结果说明了性能和接收机复杂性之间的权衡。
The performance of a single-user ultra-wideband (UWB) communication system employing binary block-coded pulse-position modulation (PPM) and suboptimal receivers in multipath channels is considered. The receivers examined include a RAKE receiver with various diversity combining schemes and an autocorrelation receiver, which is used in conjunction with transmitted reference (TR) signaling. A general framework is provided for deriving the performance of these receivers in multipath channels corrupted by additive white Gaussian noise (AWGN). By employing previous measurements of indoor UWB channels, we obtain numerical results for several cases which illustrate the tradeoff between performance and receiver complexity.
