Fig. 5From: LLR-based coded performance analysis of cognitive dual-hop BICM systemsBER of a two-hop cognitive relay channel as a function of \(\mathbf {\overline {\gamma }_{\text {sd}}}\) using an UMTS turbo-coding scheme. With interleaver size N=320, and for δ p =d rp/d rd=0.5 and I/P=0 dB, lines correspond to the analytical results, hollow markers correspond to simulation resultsBack to article page
