In this paper, we find the optimum soft antenna selection (SAS) which maximizes the mutual information for the multiple-input multiple-output (MIMO) spatial multiplexing transmission in an interference channel. In this optimization problem, a 2-Dimensional (2D) directive interference model is used. We first find an optimal solution for SAS without applying any constraint on it and then propose a sub-optimal...
Significant capacity improvements are possible when the multiple antennas are employed at both the transmitter and receiver. However, the application of multiple antenna systems is restricted by increasing of the cost and complexity of radio frequency (RF) subsystem. The authors in J. Ahmadi-Shokouh et al. (2006) presented a novel structure which not only overcomes the aforementioned limitation but...
