— This paper addresses advanced radio resource management (RRM) algorithms for multiple-input multipleoutput (MIMO) transmission schemes in downlink OFDMA systems. The analysis c...
— In this paper we analyze the downlink OFDMA system-level performances of a 2x2 dual-stream MIMO multiuser transmission scheme under the assumptions of partial and noisy channel...
— In this paper, we consider the transmission of a Gaussian source in a multi-relay cooperative network, where limited channel state feedback is combined with separate source and...
The problem of characterizing lower bounds on data-rates needed for closed loop stability has been solved in a variety of settings. However, the available results lead to coding s...
In this paper we analyze the performance of random beamforming schemes in a multi-user Gaussian broadcast channel. Each user will have N > 1 receive antennas allowing optimal c...
