Assignee: HUAWEI TECHNOLOGIES CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 11:
12. A receiver device for a communication system, the receiver device comprising:
processing circuitry configured to:
receive a signal from a transmitter device, the received signal including a number M of symbols associated with an information message;
obtain a projection matrix, wherein the projection matrix is a concatenation of a plurality of submatrices, wherein each respective sub-matrix has the number M of rows, and wherein two columns in the same respective sub-matrix are orthogonal, and wherein two columns belonging to different respective sub-matrices have a correlation that is equal to or less than 1/√{square root over (M)};
perform iterative successive interference cancellation on the received signal based on the projection matrix so as to obtain a subset of the columns of the projection matrix; and
obtain a recovered information message based on the subset of the columns of the projection matrix.
