We introduce a new multiuser diversity scheme for interference management in cellular networks. A base station with K antennas communicates with at most K out of M mobile stations. It is proven that, if K ?? M, then K independent data streams can be transmitted to K mobile stations with no need for cooperative joint decoding by such stations. This result is based on a new multiuser diversity concept...
We introduce a new interference management technique for wireless cellular networks when the base station (BS) has K antennas and there are M mobile stations (MS), each with a single antenna. Our interference management scheme takes advantage of multiuser diversity to transmit K independent data streams to K out of M mobile stations. The new approach achieves the dirty paper coding (DPC) capacity...
We present the Protocol for multicasting over directional antennas (MODA) for mobile ad hoc networks (MANET). MODA is the first protocol for MANET's that uses directional antennas to reduce data packet overhead. Without increasing energy consumption, MODA increases the range of transmission as a result of which fewer nodes are involved in the forwarding process, which results in a reduction in data...
