A Fairness Factor of User Selection Algorithm for Downlink MU-MIMO System
Multiple-input multiple-output (MIMO) systems have drawn great attention in recent years due to their high throughput achieved in wireless systems.To reduce the space signal interference,the base station needs to perform a user selection algorithm when the number of users is greater than the number of antennas.User fairness is an important indicator in non-uniform channel.However,there is no standard to measure the user fairness.In this paper,we consider designing a fairness factor of user selection algorithm based on downlink multi-user MIMO system,and analyzing several common algorithms.The simulation results show that the factor can describe user selection algorithm fairness well.
