Abstract: PURPOSE: A decoding method based on list sphere decoding is provided to lower computational complexity by reducing the calculation number of a Euclidean distance in decoding based on a list sphere decoding technique. CONSTITUTION: The m-numbers of predetermined candidate vectors are selected by using a list sphere decoding technique in a communication system having the n-numbers of transmission-reception antennas(S110). An additional candidate vector is selected by selectively mixing one from the (N-1) numbers of the symbols included in each candidate vector and the symbol located around each candidate vector on a signal-space diagram for the n-numbers of each candidate vector(S120). The m-numbers of the candidate vectors, having a Euclidean distance closest to a reception vector, are successively selected from a vector set which is determined according to the n-numbers of the transmission-reception antennas and a modulation order(S20).
