Abstract
This paper presents the analysis of the average channel capacity and the SINR distribution for multiuser Multiple Input Multiple Output (MIMO) systems in combination with the base station based packet scheduler. The packet scheduler is used to exploit the available multiuser diversity in the time, frequency and spatial domains. The analysis model is carried out for 3 GPP LTE downlink transmission. Two Spatial Division Multiplexing (SDM) multiuser MIMO schemes in the context of LTE downlink transmission are investigated. They are Single User (SU) and Multi-user (MU) MIMO schemes. In general, the outage probability for systems using SU-MIMO scheme is larger than the one with MU-MIMO scheme. Compared with the systems without preceding, linear preceding can improve the outage probability. The paper contributions are the derivation of a mathematical expression of the SINR distribution and the average channel capacity for multiuser MIMO systems with a frequency domain packet scheduler.
