A space-like modulation method based on constellation rotation modulation

The invention discloses a space-like modulation method based on constellation rotation modulation, belonging to the technical field of wireless communication, and relates to a multiple input multipleoutput (MIMO) technology. A method of constellation rotation modulation is proposed under the condition that the OSM systemtransmitter end needs more channel information and needs to send additional information to the receiver. The invention has the beneficial effects that the transmitter end only needs to know the channel hj with the largest channel gain compared with the original OSM system OSMsystemtransmitter end, the information required by the transmitter end is greatly reduced, and the transmitter end does not need to transmit the power allocation factor to the receiver as in the OSM system. Compared with the original OSM system, the BER performance of the new system is much better than that of the original OSM system at high signal-to-noise ratio. 该发明公开了种基于星座旋转调制的类空间调制方法，属于属于无线通信技术领域，涉及多输入多输出(Multiple Inpu
