M. Nasiri Khormuji Huawei Technologies Sweden AB, Stockholm, Swedena The material in the book chapter in part is presented at VTC-spring 2015.
This chapter presents a novel multiple-access scheme for massive multiple-input multiple-output (mMIMO) communication systems. The proposed multiple-access technique hinges on semiorthogonal channel training and data transmission such that in a given time-slot some of coordinated users appear orthogonal while the remaining users transmit nonorthogonally. The scheme is coined as semiorthogonal multiple-access (SOMA). SOMA allows transmittal of additional data as well as scheduling more users for uplink transmission as compared to ...
