A cooperative precoding method, applied in a communication system comprising a coordinating device and multiple serving stations, is provided. The cooperative precoding method includes the following steps: the coordinating device obtaining multiple carrier frequency offset (CFO) parameters of the serving stations with respect to a user device; generating multiple cooperative encoded sequences; assigning the cooperative encoded sequences to the serving stations, respectively, according to an order of the plurality of CFO parameters; and the plurality of serving stations transmitting the cooperative encoded sequences, respectively, to the user device. Each cooperative encoded sequence is transmitted over multiple subcarriers.

Cooperative precoding method and communication system

The present disclosure provides a receiver. The receiver comprises an antenna, configured to receive a received signal on a downlink direction, wherein the received signal comprises an interfering downlink signal and a desired downlink signal; and a detecting circuit, coupled to the antenna, configured to perform a multiuser detection operation on the received signal on the downlink direction to generate a detected interfering signal and a detected desired signal; wherein the desired downlink signal is transmitted by a first station, intended for the receiver, and generated according to a first modulation order; wherein the interfering downlink signal is transmitted by a second station, intended for a second receiver other than the receiver, and generated according to a second modulation order.
