  3. 2. Efficient High-level Synthesis Implementation of massive MIMO Processing on RFSoC

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Sijia Cheng; [2022]
    Keywords : Technology and Engineering;

    Abstract : Massive multiple-input multiple-output (MIMO) refers to a wireless access technology that equips base station (BS) with hundreds to thousands of antennas to serve tens of user equipment (UE) in the same time-frequency resource. These extensive antennas improve spectral and energy efficiency, but the detection algorithms tend to be more complex with operations, multiplications, and inversions on larger size matrix.
