Evaluate the performance of downlink LTE systems in multi-path channels

Abstract

In this paper, we analysis the performance of Multiuser Multiple input Multiple output (MU-MIMO) Schemes in Long term evolution (LTE). As the performance metric, Block error rate and throughput are evaluated in terms of Signal to Noise Ratio (SNR) for different MIMO Schemes defined as in LTE. To achieve the high throughput required by the downlink LTE systems spatial multiplexing and transmit diversity transmission modes are used. The Block error rate (BLER) performance of the proposed systems is studied under different Multi-path channels. Simulation results show the under multipath channel, BLER of LTE system is effectively reduced by using transmission modes.
