Interference cancellation through interference alignment for downlink of cognitive cellular networks
الملخص
Interference cancellation through interference alignment (IA) at the downlink of cognitive cellular networks is proposed. IA helps the spatial resources to be shared among primary and secondary cells, and thus it can provide higher degrees of freedom (DoFs) through interference cancellation. The achievable DoFs are derived and depicted. The achievable sum rates applying water-filling optimal power allocation are analysed and calculated. The Institution of Engineering and Technology 2015.
