Performance Analysis of Pulse Position Modulation-Time Hopping Ultra Wide Band Systems with Antenna Diversity in Indoor Wireless Channel

실내 무선채널에서 안테나 다이버시티를 적용한 펄스위치변조-시간도약 초광대역 무선통신 시스템의 성능 분석

In this paper, we analyze the performance of pulse position modulation-time hopping ultra wide band (PPM-TH UWB) systems with antenna diversity technique in indoor wireless channel. A modified Saleh and Valenzuela (SV) model is adopted as a UWB indoor channel model. Perfect synchronization between a transmitter and a receiver is assumed. Therefore, coherent equal gain combining (EGC) scheme to collect the energy available in the multipath components is investigated. It is shown that the performance is improved by increasing the number of antennas at the receiver. The results of this paper can be applied to the applications of UWB.
