... proposed design in MIMO ad hoc networks. The rest of this paper is organized as follows. In Section 2, a review of the pertinent works on the precoding methods in MIMO ad hoc networks is presented. In Section ... SINR values. Thus, maintaining a minimum SINR threshold would be more efficient in boosting up the system throughput. Our proposition does not deal directly with...
