[33] considered the orthogonal beamforming systems with limited feedback under the per user unitary and rate control (PU2RC) technology, where the beamforming weights are selected from a codebook of multiple orthonormal bases in the multiuser system.
This indicates that when compared to a typical SDMA, i.e., PU2RC [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] [22], the throughput the scaling law of the spectrum sharing SDMA is (J - 1)/J times that of PU2RC with orthogonal beamforming but no transmit-null.
When compared to PU2RC [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] [22], the throughput the scaling law of the spectrum sharing SDMA is (J - 1)J times that of PU2RC.
This indicates that the spectrum sharing SDMA provides the same throughput gain from opportunistic user scheduling at the transmitter multiuser compared to PU2RC. The main performance metrics of the spectrum sharing SDMA versus P[U.sup.2]RC are summarized in Table 1.
Although the spectrum sharing SDMA has lower multiplexing gain compared to PU2RC in the non-coexistence scenario, it offers an intriguing opportunity to reuse spectrum already allocated to other coexisting services, and further always requires less feedback overhead than PU2RC.
