Performance Enhancement of UWB Power Control Using Ranging and Narrowband Interference Mitigation Technique

Power control is a critical parameter for the design and evaluation of UWB-based WPAN networks due to itsdistributed control nature and non-fixed topology. The main issues in UWB PC are the channel gain fluctuations induced byindoor channel fluctuation and interference arising from narrowband systems. In this paper we introduce a joint PHY/MACtechnique for DS-UWB power control design by exploiting the high time resolution of the UWB signal for channel gainimprovement and mitigate the narrowband interference to reduce transmitted power. The results indicate that the proposedapproach achieves better BER and throughput over previous works
