  • Method for slicing K-best detection in multiple-input multiple-output wireless communications system
    Patent number: 10374772
    Abstract: In a MIMO detector, a slicing list detection scheme employs a complex plane to represent symbols in an alphabet, in which all decision regions are bounded by either vertical lines or horizontal lines. A K-best scheme accesses the complex plane and an offline-generated lookup table to detect elements of a received vector. At each level, the system prunes all but the K-best candidates from each surviving node through the slicing list detector.
    Type: Grant
