Abstract
The present invention relates to a method for detecting a signal, a device for detecting a signal, and a receiving device. A method for detecting a signal according to the present invention is a method for detecting a signal from a receiving device in a communication system including a multi-output multi-input antenna, including: estimating a channel matrix of a signal received from a plurality of receiving antennas; generating at least one channel matrix groups by aligning the channel matrix and generating at least one transmitting signal group by aligning a transmitting signal to be estimated to correspond thereto; determining a first candidate vector in consideration of all constellation points for a first layer of the at least one transmitting signal group; determining a second candidate vector in consideration of all constellation points for a second layer of the at least one transmitting signal group; generating a final candidate vector including the first candidate vector and the second candidate vector; and calculating a soft output using the final candidate vector.
