摘要： 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.

摘要： 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.
