SIGNAL PROCESSING METHOD AND RELATED EQUIPMENT

摘要

Disclosed are a signal processing method and related equipment, which are used for reducing the number of antennas needed by a near end user equipment to detect a low power signal. The method according to embodiments of the present invention comprises: a base station adjusting a pre-coding vector of a high power data stream, so that the pre-coding vector multiplied by an effective receiving channel of a low power data stream equals a constant; the base station performing superposition coding on the low power data stream and the adjusted high power data stream; the base station sending the data stream after the superposition coding to user equipments, wherein the user equipments comprise a cell center user equipment and a cell edge user equipment, the high power data stream is an interference signal for the cell center user equipment, and the low power data stream is a useful signal for the cell center user equipment.
