Abstract

Multipath detection is very important for the proper operation of wideband communication systems. Conventional detectors using constant threshold result in suboptimal performance since they either fail to detect a multipath component or provide a wrong path to the receiver. In this paper, two adaptive constant false alarm rate (CFAR) multipath detectors are proposed: cell-averaging CA-CFAR and order-statistics OS-CFAR. An experimental indoor wideband communication system operating at the 5 GHz range has been implemented to collect real data for use by the proposed CFAR detectors. Details of the implemented system and experimental results are presented in this paper. It is observed that the OS-CFAR detector outperforms the CA-CFAR in terms of detection capability.
