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

    University essay from Linköpings universitet/Kommunikationssystem

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

    Abstract : 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].

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

    Author : Kishore Khed; [2018]
    Keywords : Technology and Engineering;

    Abstract : Internet of Things (IoT) is a network constituted by uniquely identifiable commodity objects or devices equipped with some sensing system. To achieve high data rates required for IoT devices, a modern wireless communication system, known as Advanced Antenna Systems(AAS), leads to significant improvement, by increasing not only the data rate but also spectrum efficiency and the channel capacity.

  6. 40. Electromagnetic analysis of AES-256 on Xilinx Artix-7

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

    Author : Oskar Westman; [2018]
    Keywords : Electromagnetic side-channel attack; AES-256; Artix-7; FPGA; Differential analysis; Simple analysis.; Technology and Engineering;

    Abstract : In this project, an electromagnetic side-channel attack has been made by exploiting the information leakage from a field programmable gate array (FPGA) and an implemented advanced encryption standard with a 256-bit key (AES-256). The FPGA-board was a Nexys-4 from Digilent with Artix-7 FPGA. The attack was partially successful. READ MORE
