经典的频谱共享的EI检索算法，运用动态频谱租用来提高频谱利用率。-Dynamic Spectrum Leasing (DSL) is a new

paradigm for efficient spectrum sharing in cognitive radio

networks that was recently proposed in [1]–[3]. Unlike in a

hierarchical dynamic spectrum access (DSA) network, DSL

allows active participation of both the primary and the secondary

users in the spectrum sharing process. In this paper we further

generalize the DSL game introduced in [2] by allowing for linear

multiuser detectors, in particular the matched filter (MF) and

linear minimum mean squared error (LMMSE) receivers, at the

secondary base stations. We establish the conditions so that the

DSL game has desired equilibrium properties. Performance of

the proposed system at the equilibrium is compared through

simulations
