| Summary: | A virtual MIMO scheme based on cooperation of the prim and secondary users was proposed in the wireless cognitive networks.The tight upper and lower bounds about the complimentary cumulative distribution function of the virtual MIMO signal and interference were derived.The asymptotic distributions of the bounds were also obtained.The theoretical derivations and numerical simulations testified that the upper and lower bounds had the same asymptotic distribution.The numerical simulation results reveal that the virtual MIMO technique improves the anti-interference ability of the primary signal. |
