Cognitive Radio technology will have significant impacts on upper layer performance in wireless In this paper, a jointly-optimized beam forming is applied for cognitive networks that maximize the achievable transmission rates, where primary and cognitive users share the same spectrum and are equipped with multiple antennas. With the help of beam forming signals, co users and the interference cancellation is done at the cognitive user. Specifically, the beam forming vectors of the cognitive link are designed to maximize the signal t algorithms that are need for the beam forming in the cognitive networks
