— A MIMO network is a wireless network made up of individual MIMO links. The problem we consider is to maximize throughput in a multihop MIMO network with interference suppression. Our problem formulation accounts for variable rates on the MIMO links, which depend on the channel conditions of the link, and the manner in which the diversity-multiplexing(More)
—We tackle the problem of determining the beam-forming and combining weights in a network of interfering multiple-input multiple-output (MIMO) links. We classify any strategy for computing these weights as either unilateral or bilateral. A unilateral strategy is one for which the responsibility of cancelling interference from one node to another is(More)
—We propose an algorithm to allocate streams and find the corresponding beamforming and combining weights that maximize the sum rate of a set of interfering multiple-input multiple-output (MIMO) links. Our algorithm iteratively computes the beamforming and combining weights of each link and determines how many streams, if any, are allocated to each link.(More)
—We propose an algorithm whose goal is to maximize the sum rate of a set of interfering multiple-input multiple-output (MIMO) links by jointly optimizing which subset of transmitters should transmit, the number of streams for each transmitter (if any), and the beamforming and combining weights that support those streams. We present numerical results to(More)
—This paper addresses the problem of fair scheduling of MIMO links in dense wireless network deployments where interference suppression is carried out via linear MIMO processing to optimize network performance. We formulate and solve an optimal MIMO link scheduling problem, where the goal is to maximize aggregate throughput while meeting a specified(More)
