  1. 1. Performance Analysis Of Massive MIMO With Port Reduction

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Tingrui Zhang; [2022]
    Keywords : 5G NR; Massive MIMO; Fronthaul; Beamforming; Functional split; 5G NR; Massive MIMO; Fronthaul; Beamforming; funktionell uppdelning;

    Abstract : In centralized radio access network (C-RAN) architecture, the base-band unit (BBU) is connected to one or more remote radio units (RRUs) via a fronthaul (FH) interface. Upgrading base station antennas in C-RAN to support massive multiple-input multiple-output (MIMO) technology can improve network spectral efficiency and largely boost the capacity of the 5G system.

  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.

  5. 4. Hybrid Coupler for LMBA Input Match Using an Active Inductor

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Karthik Doddanna; [2021]
    Keywords : LMBA; gyrator-c; active inductor; hybrid coupler; TSMC 0.18um.;

    Abstract : With the increase in demand for compact and high data rate communication systems, there is a need for high efficiency with modulated signals (PAPR 5-10 dB) for base-station power amplifiers. One of the famous architectures used to achieve this is Doherty architecture. READ MORE

  6. 5. Beyond 5G Baseband Processing on Epiphany Architecture

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Yash Sawant; [2021]
    Keywords : ;

    Abstract : Massive Multiple Input Multiple Output (mMIMO) is a key technology for wireless communications. The concept behind the technology is using a large number of antennas at the base station which servers multiple user equipment simultaneously. READ MORE
