Cognitive Radio technology will have significant im pacts on upper layer performance in wireless optimized beam forming is applied for cognitive net works that maximize the achievable transmission rates, where primary and cognitive use rs share the same spectrum and are equipped with multiple beam forming signals, co -ordination is not required between the primary and cognitive 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 o noise ratio (SNR). This paper also deals the requ ired algorithms that are need for the beam forming in th e cognitive networks. g, Primary User, Cognitive User .
