The present invention provides a signal detection method and device, electronic equipment, and a readable storage medium, including: detecting a received modulated signal to obtain a first solution of the target transmission layer; according to the first solution and the target transmission layer The first constellation diagram of the target transmission layer is used to determine the initial estimated constellation point of the target transmission layer; according to the initial estimated constellation point, the second constellation diagram of the target transmission layer is determined, and the second constellation diagram is the first A subset of constellation diagrams: based on the second constellation diagram, detect the modulated signal to obtain a second solution of the target transmission layer. The invention can reduce the implementation complexity of the maximum likelihood detection algorithm, and obtain better detection performance at the same time.
Description
technical field [0001] The present invention relates to the field of wireless communication, and in particular, to a signal detection method and device, an electronic device, and a readable storage medium. Background technique [0002] The increased demand for data transmission in wireless communication systems has increased the demand for higher throughput systems. Higher order modulation and / or MIMO techniques can address the need for high throughput. For example, the 3rd Generation Partnership Project (3GPP) group has adopted 256QAM signaling in LTE Release 12 to increase system throughput, and the Institute of Electrical and Electronics Engineers (IEEE) has adopted 1024QAM in the 802.11ax standard to further increase throughput. [0003] MIMO (Multiple-Input Multiple-Output) technology refers to the use of multiple transmitting antennas and receiving antennas at the transmitting end and the receiving end, respectively. MIMO technology essentially provides spatial multi...
