  1. 11. Efficient Modelling and Performance Analysis of Wideband Communication Receivers

    University essay from Signaler och System

    Author : Andreas Eriksson; [2011]
    Keywords : performance analysis; ultra wideband; monte carlo method;

    Abstract : This thesis deals with Symbol Error Rate (SER)-simulation of wireless communications and its application into throughput analysis of UltraWideband (UWB) systems. The SERs will be simulated in C++ using the Monte Carlo method and when some are calculated, the rest will be estimated using a novel extrapolation method. READ MORE

  4. 13. Channel Estimation Techniques of SC-FDMA

    University essay from Karlstads universitet/Fakulteten för teknik- och naturvetenskap

    Author : Jin Xinzhu; [2007]
    Keywords : Electrical Engineering; Wireless Communication; Signal Processing;

    Abstract : Abstract This master thesis investigates several di®erent channel estimation techniques in an SC- FDMA (Single Carrier Frequency Division Multiple Access) system with parameters set according to the standards of 3GPP LTE (3rd Generation Partnership Project Long Term Evolution). 3GPP LTE is the name given to a project within the 3GPP to improve the mobile phone standard to cope with future requirements.

  5. 14. Modeling and Prediction of Radio Channels for Orthogonal Frequency Division Multiplexing

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Per-Ola Larsson; [2005]
    Keywords : Technology and Engineering;

    Abstract : In a wireless communication system, the channel is ever changing due to multipath properties such as excess delays and constructive and destructive interference. In a step to optimize system performance, it would be beneficial to have access to channel state information of both present subchannels' future development and subchannels outside the currently used frequency interval.
