Capacity Analysis for Correlated MISO Channels in the Presence of Correlated Interference and Noise

Exact and general analysis of the capacity for multiple-input single-output (MISO) correlated Rayleigh fading channels in the presence of both correlated Rayleigh co-channel interference and additive Gaussian noise is not available in the literature, although its counterpart with Gaussian noise alone has been thoroughly investigated. The difficulty arises from the quadratic form of interference term. In this paper, we obtain exact solutions to the ergodic capacity for MISO systems with and without channel state information (CSI) at the transmitter. Numerical results are also presented for illustration.
