Threshold Profiling for Wideband Ranging

This letter establishes a methodology to design threshold profiles for wideband ranging systems. Differently from conventional methods using a single threshold value that is designed based on the signal detection and false-alarm probability requirements, we propose a threshold profile that is designed based also on the ranging error requirement. The proposed method relies only on channel statistics without requiring channel estimation. A case study shows that, compared to conventional methods, the proposed method for threshold profiling significantly improves the performance in terms of false-alarm probability, detection probability, and ranging error.
