借鉴传输参考信号的思想,将其扩展到一组多个信号,提出一种新型超宽带(UW B)差分相关接收机。理论性能分析和UW B室内多径信道仿真表明:该接收机的检测性能优于传统的自相关接收机,尤其是在0~4 m近距离时,而且结构复杂度较低,便于实现。
Drawing on the idea of transmitting reference signals, this paper extends it to a group of multiple signals and proposes a new UWB differential correlation receiver. The theoretical performance analysis and UWB indoor multipath channel simulation show that the receiver has better detection performance than the traditional autocorrelation receiver, especially when it is close to 0 ~ 4m, and its structure complexity is low and it is easy to realize.
