Multiple-input multiple-output (MIMO) systems assisted by multiple relays with single antenna are considered. The signal transmission consists of two phases. In the first phase, the source node broadcasts the vector symbols to all relays, then all relays forward the symbols multiplied by gain parameters to the destination simultaneously. Unlike the case of full cooperation among relays such as a single...
Emerging systems like OFDMA and MIMO systems require multichannel scheduling over a wireless link. In this paper, we focus on the case that the number of channels to be assigned to a mobile terminal is limited, which we call limited matching. This case often occurs over a MIMO downlink when the number of receive antennas at a mobile user is smaller than that of transmit antennas at the base station...
