Impact of Narrowband Interference on Multi-Band OFDM Ultra Wideband Communication Systems

This paper analyzes the impact of narrow-band interference (NBI) on the performance of multi-band (MB) OFDM ultra wideband communication systems. A comprehensive study of the effects of NBI on the analog-to-digital converter (ADC) and carrier synchronization algorithm is presented. The overall impact of NBI is demonstrated by quantifying the MB-OFDM receiver system level performance in terms of block error rate.
