Abstract:We investigate the multiple-input multiple-output broadcast channel with channel distribution information available at the transmitter. The so-called fading-paper model is considered with N t transmit antennas, and each user having N r receive antennas. Near-optimal designs are proposed for the inflation factor matrix under general fading conditions, based on maximizing the approximation of linear assignment capacity. It is proved that for N t ≤ Nr, this matrix has a similar structure and achieves a similar in… Show more
