  1. 1. Is the Cyclic Prefix Needed in Massive MIMO?

    Master-uppsats, Linköpings universitet/Kommunikationssystem

    Författare :Valens Nsengiyumva; [2016]
    Nyckelord :Cyclic Prefix in Massive MIMO;

    Sammanfattning : Massive multiple-input-multiple-output (MIMO) is a wireless communication technologythat usesa large number of antennas at the base station and servesmultiple terminals over the same time-frequency resource.This technique can achievehigher data rates than existing communication technology, which only serves one terminal per resource.

  3. 2. Implementing Linear Predictive Coding based on a statistical model for LTE fronthaul

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Ghassan Nakkoul; Mohammad Shohag Hassan Kaikobad; [2016]
    Nyckelord :Entropy; LTE fronthaul; RRH; BBU; C-RAN; Quantization; LTE downlink; Cyclic prefix; LPC; EVM; OFDM; Linear predicting coding; LTE; Technology and Engineering;

    Sammanfattning : This thesis studies the application of Linear Predictive coding (LPC) in the downlink of Long Term Evolution (LTE) fronthaul, which comprises of BBU and RRH. This can act as an additional module in the existing system. Today, the transmission of a single complex sample from the BBU to the RRH consumes 30 bits. LÄS MER
