Summary:In this letter, we propose full-rate cooperative spectrum sharing protocol for bandwidth efficient cognitive networks. Cooperative communication is a newly emerging protocol for multiple-input multiple-output, which offers diversity and hence improves the link performance. We show that the proposed scheme enhances the spectral efficiency of the primary user and improves the spectrum usage of the secondary user through cooperative multiplexing. We present an analytical derivation for the average bit error rate of a proposed scheme with maximum likelihood receiver.
