Spectrum sensing has become one of the main components of a cognitive transmitter. Conventional detectors suffer from noise power uncertainties and multiantenna detectors have been proposed to overcome this difficulty, and to improve the detection performance. However, most of the proposed multiantenna detectors are based on non-optimal techniques, such as(More)
Pilot contamination is known to be one of the main bottlenecks in multi-cell multi-input multi-output (MIMO) networks. In this study, we investigate the effect of angular spread (AS) on the ergodic rate of a multi-cell network under pilot contamination, considering correlated MIMO channels and moderate antenna array sizes. We derive an exact expression for(More)
