Abstract

The existing cognitive network can’t work together with licensed (primary) users’ network at the same frequency-time domain, and secondary users (SUs) of cognitive network only wait the frequency band occupied by primary users (PUs) to be free. To solve the problem, this paper proposed a spatial coding approach for MIMO cognitive network, where a MIMO base-station with six antennas provides three different spatial codes for three users such as one PU and two SUs, then the SUs can share the bandwidth of PUs. The spatial codes’ design for encoding and decoding vectors is provided. Simulation results verify the proposed approach.
