UWB-IR Interference Mitigation Using Multi-Carrier Templates in Frequency Dependent Path Loss Environment

Performance degradation of UWB-IR wireless systems due to interference from co-existing services is an important issue. To reduce the effect of interference from coexisting sources such as the WLAN standard IEEE 802.11a on UWB Communication, the construction of a modified template waveform using multi-carrier sinusoids was proposed previously. However, that work considered a free space propagation channel model with no treatment of the frequency dependence of the UWB path loss. In this paper we broaden the study by taking into consideration a frequency dependent path loss environment. The novelty of the work is in the investigation of the effect of frequency and distance dependency of the path loss on the performance of interference mitigation scheme.
