This letter describes experiments conducted to measure the interference effects of two kinds of UWB sources, which are OFDM UWB source and pulse radio UWB source, to broadcasting relay system and SDMB system. The received power degradation of a broadcasting system is presented. experimental results show that UWB system can coexist 35m distance as close as to in-band broadcasting network and can also coexist 1.8m as close as with the SDMB terminal without causing any dangerous interference.
