    • A communication apparatus, method, and system are provided. The communication apparatus receives through a transmission path a combined signal in which modulated signals are combined. The communication apparatus converts a channel matrix indicating transmission characteristics of the transmission path using a basis conversion matrix which converts column vectors forming the channel matrix to cross at right angles, estimates a transmission symbol using the converted channel matrix, and calculates a likelihood of each bit of the estimated transmission symbol being a “1” and a “0”, respectively, using an inverse matrix of the basis conversion matrix. The method includes converting a channel matrix; estimating a transmission symbol; and calculating a likelihood of each bit being a “1” and a “0”, respectively, of the estimated transmission symbol using a basis conversion matrix. The system includes a transmitter and receiver for transmitting and receiving, respectively, a combined signal according to the method.
