  1. 16. Statistical Approach for the Design of Refresh-Free eDRAM with Retention Timing Constraint

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

    Författare :Arturo Prieto; [2019]
    Nyckelord :Memory; eDRAM; DRAM; SRAM; IC; Refresh; Statistics; Importance Sampling; Monte Carlo; Technology and Engineering;

    Sammanfattning : In digital integrated circuits, memories are often a limiter for main performance, power and area. Over the past decade, integrated memories have gained dominance in terms of area and power cost. In applications like machine learning or image processing the area share can be above 80% consuming more than 50% of the total power budget. LÄS MER

  5. 19. Analysis and Compensationfor Clipping-like Distortion of the Transmitted Signal in Massive MIMO Systems

    Master-uppsats, Linköpings universitet/Kommunikationssystem

    Författare :Adel Fayad; [2018]
    Nyckelord :Master; Thesis; Massive MIMO; Clipping; Distortion; Power amplifier distortion; SNR; Error Probability;

    Sammanfattning : This project consists of analyzing and finding solutions to the effect of non-linear distortionon the performance of a Massive Multiple Input Multiple Output (MIMO) system interms of Spectral Efficiency (SE) and Symbol Error Rate (SER). Massive MIMO is one ofthe technologies that are considered the backbone of the 5th generation of wireless communicationsand therefore this technology has gathered much interest from researchersand companies alike [19], as it is proven that this kind of system greatly improves thecapacity of the wireless connection [8].

  7. 20. Estimation of Statistical Properties in a Mobile MIMO System

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Torsten Molitor; Hilding Wollbo; [2018]
    Nyckelord :;

    Sammanfattning : Several measures to evaluate the stationarity of a MIMO radio channel are proposed and implemented. The analysis is performed on a Kronecker model implementation of the channel matrix covariance, which describes the statistical characteristics and transmission properties of the radio channel.
