Abstract:

The performance of peak detection of ultra-wide band receiver is greatly affected by the threshold of the comparator. Considering that the bit error rate is a convex function of the threshold, we propose a dynamic threshold control based on training sequence. The simulation results show that the proposed practical algorithm can track and approach the optimal comparator threshold to achieve better reception performance.

Key words: peak detection, ultra-wide band, convex, training sequence, dynamic threshold control
