Multiple antenna spectrum sensing in cognitive radios
In this paper, we consider the problem of spectrum sensing by using multiple antenna in cognitive radios when the noise and the primary user signal are assumed as independent compl...

Diversity-Multiplexing Tradeoff in Half-Duplex Relay Systems
β€” We study the multiple antenna half-duplex relay channel from the diversity-multiplexing tradeoff (DMT) perspective. We find performance upper bounds and show that compress-and...
