Abstract

A distributed algorithm, which exploits channel state information (CSI) at the transmitter, is presented for determining the maximum number of independent data streams for each transmitting node in a network of interfering multiple-input multiple-output (MIMO) links. Simulated throughputs for two simple network topologies show that the algorithm yields nearly optimal stream control. These closed-loop MIMO throughputs are compared to those of open-loop MIMO, with and without optimal stream control, and to the throughput when the links operate in a non-interfering, TDMA fashion.
