  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

  3. 12. High Level Ultra Low Power Transmitters for the MICS Standard

    University essay from Elektroniska komponenter

    Author : Per Eidenvall; Nils Gran; [2010]
    Keywords : Ultra Low Power; MICS; PSK; QPSK; Radio Transmitter; QPSK Modulator;

    Abstract : Today, medical implants such as cardiac pacemakers, neurostimulators, hearing aids anddrug delivery systems are increasinglymore important and frequently used in the health caresystem. This type of devices have historically used inductive coupling as communicationmedium. READ MORE

  4. 13. M-PSK and M-QAM Modulation/Demodulation of UWB Signal Using Six-Port Correlator

    University essay from Fysik och elektroteknik

    Author : Negar A. Sani; [2010]
    Keywords : Six-Port Correlator; Ultra Wideband; Wireless Communication; Modulation; Demodulation; M-QAM; M-PSK;

    Abstract : Nowadays high speed and high data rate communication are highly demanded. Consequently, wideband and high frequency transmitter and receivers should be designed. New transmitters and receivers should also have low power consumption, simple design and low manufacturing price in order to fulfill manufacturers’ requests for mass production. READ MORE

  5. 14. Increasing Accuracy of Location Determination : Exploiting Phase Change Reconstruction and Timing Measurements

    University essay from KTH/Kommunikationssystem, CoS

    Author : Lin Ji; [2007]
    Keywords : IEEE 802.11b; Correlation; Time stamping; FPGA; PSK; IEEE 802.11b; korrelation; Tidstämpel; FPGA; PSK;

    Abstract : The thesis deals with improving location determination when using time of flight of radio signals to determine the location of a radiator. The goal of this project is to enhance an existing wireless data access point to perform an accurate measurement of the time of arrival of a data signal from a transmitter, and to combine this information with information from additional wireless data access points to determine the location of the transmitter.

  6. 15. Efficient Message Passing Decoding Using Vector-based Messages

    University essay from Institutionen för systemteknik

    Author : Mikael Grimnell; Mats Tjäder; [2005]
    Keywords : Forward Error Correction; Low Density Parity Check Codes; Message Passing Decoding; Belief Propagation; Extrinsic Information Transfer; Galois Fields; Phase Shift Keying;

    Abstract : The family of Low Density Parity Check (LDPC) codes is a strong candidate to be used as Forward Error Correction (FEC) in future communication systems due to its strong error correction capability. Most LDPC decoders use the Message Passing algorithm for decoding, which is an iterative algorithm that passes messages between its variable nodes and check nodes. READ MORE
