Exact matchings have been extensively studied in the past, but there is relatively little work about approximate matchings. We present a throughput analysis when random arbitration is used to obtain approximate matchings. We compute the throughput by the average available credits at outputs, which is obtained through a DTMC modeling. We also devise an iterative solving procedure for the DTMC of available...
This paper develops bit and power allocation schemes with beamforming for multi-cell orthogonal frequency division multiplexing (OFDM) systems on uplink. The model of the multi-cell channel with frequency reuse is considered. The transmit signal from each mobile causes interference to the received signals of other base stations. The schemes aim to minimise the total mobile transmit power while satisfying...
