Analysis of Channel Capacity for LTE Downlink Multiuser MIMO Systems

The average channel capacity for 3GPP LTE downlink multiuser Multiple Input Multiple Output (MIMO) systems is analyzed in this paper. A packet scheduler is used to exploit the available multiuser diversity in all the three physical domains (i.e., space, time and frequency). A mathematical model is established to derive the channel capacity of multiuser MIMO systems with the Frequency Domain Packet Scheduler (FDPS). This paper provides a theoretical reference for the future version of the LTE standard and a useful source of information for the practical implementation of the LTE systems.
