  • Abstract
    Interference alignment (IA) is a data transmission scheme that achieves maximum multiplexing gains in interference channel. This study investigates the theoretical sum rate for IA. By analysing both the asymptotic eigenvalues distribution and the magnitude of the effective channel after interference cancellation in IA, a closed-form of sum rate expression is derived for Gaussian interference channel. Numerical results show that the closed-form results nearly coincide with that derived from numerical results of IA.
