Description
technical field [0001] The invention relates to the field of wireless communication, in particular to a signal detection method and device, electronic equipment, and a readable storage medium. Background technique [0002] The increased demand for data transmission in wireless communication systems has led to an increased 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) has adopted 256QAM signals in LTE Release 12 to increase system throughput, and the Institute of Electrical and Electronics Engineers (IEEE) has also 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 receiving end respectively. Its starting point is to use multiple input and multiple output to...
