Achieving Near-Capacity at Low SNR on a Multiple-Antenna Multiple-User Channel
We analyze the sensitivity of the capacity of a multi-antenna multi-user system to the number of users being served. We show analytically that, for a given desired sum-rate, the e...

Power Scheduling for MIMO Relay Channels Employing Rateless Codes
—We propose a simple power scheduling algorithm for relay channels with multiple antennas. The algorithm combines seamlessly with a low complexity communication protocol that emp...
