MIMO CHANNAL:
AN interesting model to study the effect of interference in communication systems is the single antenna two user interference channel, consisting of two point-to-point links which interfere with each other.sum-rate capacity of the IC is characterized in the low-interference regime: a regime where using Gaussian inputs and treating interference as noise is optimal.By allowing messages on all the links of the IC, we obtain the X channel, i.e., both transmitters have an independent message for each receiver, for a total of four messages in the channel In this sense, the X channel (XC) is a generalization of the IC.
