Abstract
In Cognitive radio (CR) applicationsUltra-wideband (UWB) impulse radio (IR)signals can be designed such as they can co-exist with licensed primary users. Thepulse shape should be adjusted such that the power spectral characteristics not only meet the Federal Communications Commission (FCC) constrains, but also mitigate multiple narrow -band interference at the locations of existing primary users. In this paper, the Parks-McClellan (PM) Algorithm and the Eigen Value Decomposition (EVD) approach for UWB impulse radio waveform shaping areconsidered. The power spectral density (PSD) and the bit -errorrate (BER) performance of the two methods are compared in the presence of single and double narrowband interference (NBI). The interference rejection capabilities of the two methods are evalua ted and compared for different interference and additive noise levels. In particular, the simulations considerthe coexistence of practical IEEE 802.15.4a UWB systems with both IEEE 802.11 wireless LAN systems operating at 5.2 GHz and radio location servic es operating at 8.5 GHz.
