METHOD AND EQUIPMENT FOR SIGNAL DECTECTION IN MULTI-INPUT MULTI-OUTPUT SYSTEM

摘要

A method and equipment for signal detection in a multi-input multi-output system, the method includes: carrying triangular factorization to a channel matrix of an MIMO system, dividing the MIMO system into a plurality of MIMO sub-systems; detecting a receiving signal vector of the first sub-system to obtain a candidate detection vector list of the sub-system; detecting other sub-systems in the manner of interference cancellation to obtain the candidate detection vector lists of other sub-systems; judging or calculating to obtain the transmission signal vector of the MIMO system after combining all the lists.
