ABSTRACT:
Apparatuses and methods for cancelling interferences between signals are provided. The apparatuses includes: a receiving unit that receives an orthogonal coded signal from a transmitter and generates a received vector; a channel estimation unit that estimates a state of a wireless channel from the transmitter to the apparatus where the cancelling of the interference between signals is performed and generates a channel state matrix; a Q-R decomposition unit that performs Q-R decomposition with respect to the generated channel state matrix and generates a Q matrix and an R matrix, and generates a decision statistic vector based on the generated Q matrix and the received vector; and a signal determination unit that determines a received signal with interference from the orthogonal coded signal being decreased based on the generated decision statistics vector.
