摘要
A method of mitigating narrow band interference (NBI) in ultra wide band (UWB) systems operating around 10 GHz mitigates multiuser interference from IEEE 802.22 and WiMAX, wherein the multiuser interference interfers with both trained and blind UWB systems, with the trained UWB system using pilot symbol assisted modulation. The method passes a received UWB signal through a band pass filter (BPF), wherein the BPF is located at a UWB receiver and the UWB signal is a Hanning modulated pulse centered at 4 GHz frequency. The method further measures a plurality of test functions, determines a number of active users, notch filters NBI signals, based on the determined number of active users, passes the notch filtered signal through a quadratic programming algorithm, to perform joint decoding, estimates an arrival of a UWB payload, and demodulates the UWB payload, based on the estimated arrival of the UWB payload.
