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