Abstract: The present disclosure relates to a method and device for signal processing in a communication system. The present disclosure uses orthogonal and quasi-orthogonal spreading sequences and spatial channels to discriminate data of a terminal device. Since the spreading sequences utilized by data of the same terminal device are orthogonal, interference from the user itself is eliminated. As spreading sequences utilized by different terminal devices are quasi-orthogonal, interference between users is inhibited through spatial channels. Compared with other non-orthogonal multi-user access scheme, the present disclosure increase the supported overloading factor by combining the orthogonal spreading sequences and spatial channels.
