A new method is proposed to determine precoding

matrices that achieve local maxima of the expected sum rate in

a multiple input multiple output interference channel (MIMO

IC), in the realistic scenario where only partial channel state

information (CSI) is available at the transmitters. Relying on

a random matrix analysis of the capacity of large dimensional

Ricean channels introduced in [1], the expected sum rate of the

K-user MIMO IC is approximated by a deterministic equivalent

to which an iterative gradient scheme is applied to find local

maxima of the approximated sum rate.
