Abstract
Provided are a multi-user multiple-input multiple-output detection method and apparatus, an electronic device, and a computer-readable storage medium. The method includes: in a case where it is determined that received data includes data for first user equipment and data for at least one second user equipment, determining a first detection method according to a modulation mode of the first user equipment (100); and performing multi-user joint detection on the received data with the first detection method (101).
Claims13
A multi-user multiple-input multiple-output detection method applicable to first user equipment, comprising:
- in a case where it is determined that received data includes data for the first user equipment and data for at least one second user equipment, determining a first detection method according to a modulation mode of the first user equipment;
- and
- performing multi-user joint detection on the received data with the first detection method,
- wherein determining the first detection method according to the modulation mode of the first user equipment comprises:
- in a case where the modulation mode of the first user equipment is a low modulation mode, determining that the first detection method is a detection method of Sphere Decoding-low modulation mode, wherein in a process of performing the multi-user joint detection on the received data with the first detection method, the modulation mode of the at least one second user equipment is set to be the same as the modulation mode of the first user equipment;
- and
- in a case where the modulation mode of the first user equipment is a high modulation mode, determining that the first detection method is a Minimum Mean Square Error detection method.
A multiple-user multiple-input multiple-output detection apparatus, comprising:
- a selector configured to determine, in a case where it is determined that received data comprises data for first user equipment and data for at least one second user equipment, a first detection method according to a modulation mode of the first user equipment;
- and
- a detector configured to perform multi-user joint detection on the received data with the first detection method,
- wherein the selector is further configured to:
- in a case where the modulation mode of the first user equipment is a low modulation mode and the first user equipment cannot acquire modulation mode of the at least one second user equipment, determine that the first detection method is a detection method of Sphere Decoding-low modulation mode, wherein in a process of performing the multi-user joint detection on the received data with the first detection method, the modulation mode of the at least one second user equipment is set to be the same as the modulation mode of the first user equipment;
- and
- in a case where the modulation mode of the first user equipment is a high modulation mode, determine that the first detection method is a Minimum Mean Square Error detection method.
