Performance improvement of multiuser MIMO system based on concept of stable marriage problem

摘要

This paper presents an efficient node pair selection scheme in multiuser MIMO communication network with plural transmitters and receivers based on concept of stable marriage problem. The first step is determination of the order of preference in both of transmitter and receiver sides, and for this aim, five types of metrics derived from channel matrices are considered. The second step is node pair selection using Gale-Shapley algorithm based on the preference order. Computer simulations show that the node pairs obtained by the proposed method can achieve higher performance with quite low additional computations.
