Abstract

Software defined radio (SDR) and multiple-antenna (MIMO) techniques have been of great interest recently. In this paper, we combine the flexibility of SDR with the channel capacity gain of MIMO to achieve an optimized scheme for future communication systems. Subject to limited spectrum resources and specified quality-of-service (QoS) constraints, our scheme maps the required services onto the available frequency bands in an optimized way. We make use of the recently proposed tunable channel decomposition (TCD) to partition the MIMO channel into subchannels having prescribed gains. As a result, the proposed technique determines the optimum subchannel allocation requiring the minimum transmitting power.
