In order to meet the requirements of high data rate and high system capacity
MIMO are adopted in LTE system.The performance of MIMO detection algorithms will directly affect the overall system performance.In this paper
we describe ZF
MMSE、OSIC and Turbo iterative detection algorithms in LTE system
and conduct link level simulation of LTE downlink.The simulation results show that the Turbo iterative detection algorithm has the best detection performance
and two iterations are enough to attain good performance.And the detection performance of MMSE-OSIC
