Effect of interference from other radio system to UWB impulse radio

摘要

This paper discusses the effects of interference from other systems to UWB impulse radio system. The pulse is modulated by Bi-phase, is not adopted any multiplexing. Various interfering Systems, such as BPSK, CW; multi-carrier OFDM are assumed and bit error rate performances of UWB system are evaluated by computer simulation. As a result, the bit error rate is different as the bandwidth, modulation type and number of carrier of interfering signals. Also evaluated are the effects of filtering for rejecting interfering signals.
