Performance of Chirp Code-Orthogonalized Transmitted-Reference Ultra-Wideband system in presence of interference

Based on the research of anti-interference performance of IR-UWB, this paper studies the performance of a new kind of Chirp Code-Orthogonalized Transmitted-Reference Ultra-Wideband (Chirp-COTR-UWB) system in presence of single frequency interference, facing the application demands of expand distance UWB wireless communication. The output component expression of Chirp-COTR-UWB receivers in presence of single frequency interference is deduced in detail. In addition, in presence of narrowband jamming signal, the performances of Chirp-COTR-UWB are simulated and analysised.
