Assuming perfect channel state information, the existing interference alignment (IA) algorithm proposed in [2] suppresses inter-cell interference (ICI) by aligning ICI to a randomly selected reference vector. However, IA in practice relies on limited feedback, resulting in residual ICI. In this letter, we propose the optimization of the reference vector for(More)
—In this paper, a new subcarrier allocation algorithm is proposed for an uplink multiuser OFDM relay network. To achieve fairness for a source and relay, we consider the minimum rate requirement for a source and the power constraint on a relay, respectively. An optimization problem with fairness constraints is formulated and the subcarrier allocation(More)
— We present a new wireless scheduling algorithm based on the cumulative distribution function (cdf) of user transmission rates and also present a simple modification of it to limit the maximum starving time. This cdf-based scheduling (CS) algorithm selects the user for transmission based on the cdf of user rates in such a way that the user whose rate is(More)
