SIGNAL RECEIVING AND SENDING METHODS, TRANSMITTER, RECEIVER, AND SYSTEM THEREOF

摘要

Embodiments of the present invention provide a signal receiving method, a signal sending method, a transmitter, a receiver, and a system thereof. The signal receiving method comprises: respectively performing analog beamforming (ABF) processing on M channels of signals received by a plurality of antenna elements, M being a natural number greater than or equal to 2; respectively performing digital beamforming (DBF) processing on N channels of the M-channel signals after the ABF processing, N being a natural number greater than or equal to 2; and performing decoding processing on the signals after the DBF processing. Therefore, desirable performance can be achieved, and meanwhile, the costs can be reduced, thereby improving the cost-effectiveness.
