Abstract

The analysis and optimization of a notch filter to combat in-band narrowband interference (NBI) for multiband orthogonal frequency division multiplexing (MB-OFDM)-based ultra-wideband (UWB) systems is presented. Unintentional radiation of electronic devices can reside in the UWB band and jam the communication. Erasing the interference with a programmable analog notch filter reduces the requirement for the analog-to-digital converter resolution in the presence of NBI. The order and approximation of the notch filter are determined, and the filter's bandwidth is optimized to minimize the packet error rate. Simulation results indicate that the UWB system with suppression scheme can handle up to 14 dB more in-band interference power.
