A METHOD AND DEVICE FOR DETERMINING ANTENNA SELECTION SCHEME AND DETECTING SIGNALS

摘要

A method for determining an antenna selection scheme in a multi- antenna communication system iterates an intermediate variable related to an decompose factor matrix of more emission antennae by use of the decompose factor matrix of estimation error covariance matrix of less emission antennae, compares all the SINRs -- received signal and interference-to-noise ratio of the selected emission antennae in all the antennae selection schemes and determines an antenna selection scheme according to the comparing result of SINR. A signal detection method in a multi- antenna communication system includes: iterating the decompose factor matrix needed by the detection signal by use of the decompose factor matrix of estimation error covariance matrix of emission antennae obtained in the process of comparing SINR, or by use of the decompose factor matrix and the concerned intermediate variable with the decompose factor matrix, calculating a zero-forcing vector of each emission antenna which is detected and detecting the signals transmitted by the emission antennae with zero-forcing vector. The devices for determining an antenna selection scheme and detecting signals are also provided.
