Abstract:
1. A method for detecting signals of a Multi-Input Multi-Output (MIMO) system, comprising: performing triangular decomposition on a channel matrix of the MIMO system; decomposing the MIMO system into multiple MIMO subsystems; detecting a receiving signal vector of a first MIMO subsystem among the multiple MIMO subsystems, wherein said detecting the receiving signal vector of the first MIMO subsystem among the multiple MIMO subsystems comprises: generating a candidate detection vector list of the first MIMO subsystem according to the detection result, wherein generating the candidate detection vector list of the first MIMO subsystem according to the detection result comprises selecting multiple vectors to form the candidate detection vector list of the first MIMO subsystem according to the detection result, wherein a distance between each of the multiple vectors and a lattice of the detection result is less than a preset value; detecting remaining MIMO subsystems consecutively in a Successive Interference Cancellation (SIC) mode; generating candidate detection vector lists of the remaining MIMO subsystems; combining corresponding members of the generated candidate detection vector lists of all MIMO subsystems to obtain a candidate detection vector list of the MIMO system; and making a decision for or performing a calculation on the candidate detection vector list of the MIMO system to obtain a transmitting signal vector of the MIMO system.
