In high data rate indoor ultra wideband (UWB) communication systems, the selection of the appropriate detection method in the receiver is always an important problem. This paper compares the performances of two different detection methods, hard decision detection (HDD) and soft decision detection (SDD), for three different types of indoor UWB systems named time hopping pulse position modulation (TH-PPM),...
This paper demonstrates performance comparison of ultra wideband (UWB) systems in the stochastic tapped delay line (STDL) and IEEE 802.15.3a models of the UWB channel with RAKE receiver in presence of multiple user interference (MUI). System models are based on direct sequence code division multiple access (DS-CDMA) principle with bi-phase modulation (BPM). The system has been studied in presence...
