Throughputs and BICM capacities of a two-hop cognitive relay channel as a function of \(\mathbf {\overline {\gamma }_{\text {sd}}}\), for different relay positions δ r and fixed ratio δ p = d rp / d rd = 1. For different relay positions δ r =d sr/d sd, lines correspond to the analytical results, filled markers correspond to simulation results obtained using the exact L values, and hollow markers correspond to simulation results obtained using the max-log approximation of L value ([9], Eq. (8))
