Abstract
The frequency bands used by secondary user systems such as cognitive radio and ultrawideband (UWB) systems are subject to various forms of nonGaussian noise and interference including cochannel and narrowband interference caused by the primary user and other secondary users as well as manmade impulsive noise. For secondary user systems employing popular bitinterleaved coded modulation (BICM) we propose a robust Lpnorm metric for Viterbi decoding to overcome the harmful effects of nonGaussian noise and interference. For the resulting system, we derive an approximate upper bound on the bit error rate (BER) and a general analytical expression for the asymptotic BER valid for all practically relevant types of fading, including Rayleigh, Ricean, Nakagami m, Nakagamiq, and Weibull fading, and all types of noise and interference with finite moments. Simulation and analytical results show that, in nonGaussian noise and interference, the proposed Lpnorm metric yields large performance gains over the conventional L2norm metric and outperforms erasure decoding. © 2006 IEEE.
