In order to meet future market demand for mobile communications , the Third Generation Partnership Project 3GPP start for 3G Long Term Evolution (LTE, Long Term Evolution) project . LTE uplink in order to increase the capacity of the system uses a virtual MIMO (Multiple Input Multiple Output) techniques , then the receiving end needs MIMO detection algorithm to detect the information of different users , and therefore this study LTE uplink MIMO detection algorithms . In this paper, the MIMO detection algorithms analyze the zero-forcing , minimum mean square error on the basis of , in accordance with the characteristics of the LTE uplink system , the design used in the LTE uplink serial interference detection algorithm to eliminate (SIC, Successive Interference Cancellation) , and proposed an improved in SiC algorithm based on sort-based the SIC algorithm ( the OSIC for Ordered SIC) , this algorithm is based on interference to eliminate ideological , will eliminate the signal detected from the received signal , reduce the treatment detection signal interference , inhibit the propagation of errors and reduce the error rate of the system . This article by simulation , analysis and comparison of the BER performance of MIMO detection algorithm mentioned above , the simulation results verify that the SIC -based sorting algorithm has better performance .
