This paper presents an ultrawide-band (UWB) channel sounding scheme with a technique for estimating time of arrival (TOA) and angle of arrival (AOA) using an antenna array time domain smoothing. The smoothing averages over the time domain UWB signals of several immediate neighbor elements of the array, which is expected to be similar to the increasing number of snapshots as well as the mitigation...
This paper reports on the study of the interference effects from 4 types of ultra wideband (UWB) sources on a QPSK transmission system by simulation. The culprit UWB sources were: multi-band orthogonal frequency-division multiple-access (MB-OFDM), direct-sequence code division multiple access (DS-CDMA), DS spread spectrum UWB (DS-SS UWB), and additive white Gaussian noise (AWGN). The MB-OFDM and DS-CDMA...
