Opportunistic Beamforming using Dumb Basis Patterns in Multiple Access Cognitive Channels

Abstract

In this paper, we investigate multiuser diversity in interference-limited Multiple Access (MAC) underlay cognitive channels with Line-of-Sight interference (LoS) from the secondary to the primary network. It is shown that for N secondary users, and assuming Rician interference channels, the secondary sum capacity scales like log (
