Center node: "outage behavior of randomly precoded integer forcing over mimo channels"
  Abstract: Integer forcing is an equalization scheme for the multiple-input multiple-output (MIMO) communication channel that has been demonstrated to allow operating close to capacity for "most" MIMO channels. In this work, the measure of "bad" channels is quantified by considering a compound channel setting where the transmitter communicates over a fixed channel but knows only its mutual information. The transmitter encodes the data into independent streams, all taken from the same linear code. The coded streams are then precoded using a unitary matrix. At the receiver side, integer-forcing equalization is applied, followed by standard single-stream decoding. Considering precoding matrices being drawn from a random ensemble, outage corresponds to the event that the target rate exceeds the achievable rate of integer forcing for a given precoding matrix realization. Assuming precoding matrices drawn from the circular unitary ensemble, an explicit universal bound on the outage probability for a given target rate is derived that holds for any channel in the compound class. The derived bound depends only on the gap-to-capacity and number of transmit antennas, and is tight enough to be of interest for moderate values of capacity. The results are also applied to obtain universal bounds on the gap-to-capacity of MIMO closed-loop multicast, achievable via precoded integer forcing.
