Embodiment Construction
[0033] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.
[0034] The invention provides a detection method and a detector for receiving signals in a MIMO system, and the method and detector are applicable to other communication systems that can be modeled as MIMO.
[0035] figure 1 is the basic principle block diagram of the MIMO system, the number of transmitting antennas is N, and the number of receiving antennas is M. At the transmitting end, the high-speed data bit stream is serially converted into N low-speed data streams, and each data bit stream is modulated and transmitted from different antennas at the same time; after the wireless channel fades, the signals and noises from different transmitting antennas are superimposed After being received by multiple antennas at the same time, the MIMO detector uses the channel state information generated by the channel estimation module to reco...
