We study the uplink of a linear cellular model featuring short range inter-cell interference. Specifically, we consider a K-transmitter/K-receiver interference network where the signal transmitted by a given transmitter is interfered by the signal sent by the transmitter to its left. We assume that each transmitter has side-information consisting of the messages of the J?? users to its left and the...
We first review recent developments in multiple-input multiple-output (MIMO) techniques for mobile WiMAX systems and discuss full-rate and high-rate space-time codes of low decoder complexity. Next, we discuss the frequency reuse issue in sectored cells and point out the limitations due to overlapping of antenna radiation patterns of adjacent sectors and the resulting interference. Then, we discuss...
In this paper, we propose an efficient rate one quasi-orthogonal space-time block code for three antenna system. In order to compensate the performance degradation due to quasi-orthogonal scheme, in this proposed scheme, we incorporate a selective receiver for decoding. The receiver divides the received signals into two groups, and two receiving antennas alternatively operate to receive the divided...
