Robust GMSK Demodulation Using Demodulator Diversity and BER Estimation

This research investigates robust demodulation of Gaussian Minimum Shift Keying (GMSK) signals, using demodulator diversity and real-time bit-error-rate (BER) estimation. GMSK is particularly important because of its use in prominent wireless standards around the world (GSM, DECT, CDPD, DCS1800, and PCS1900). The dissertation begins with a literature review of GMSK demodulation techniques (cohe...

On the modelling of GMSK binary transmission over time-variant TDMA/FDD macrocellular radio channels with derotation-based coherent demodulation

(1) This work has been partially supported by the European R&D, ACTS-MOSTRAIN program. Abstract GMSK is an efficient modulation technique for digital mobile communications. In this paper a simple solution to the modeling and simulation of GMSK systems impaired by fading channels and additive white Gaussian noise is given, and its effects on the channel characteristics are also considered. The m...

10.2 Coherent Viterbi and Threshold Demodulators for Pulse-Driven GMSK Signals

Pulse-Driven Gaussian Minimum Shift Keying (PDGMSK) was introduced[1] to facilitate a trade between bandwidth efficiency and receiver complexity when using the classical GMSK waveform. The waveform was purposely devised to converge, as data rate decreases, to SDPSK or DPSK without expanding the absolute bandwidth. This paper studies the optimal coherent demodulation of the PDGMSK waveform, and ...

GMSK in a nutshell

This report presents a brief overview of the GMSK modulation scheme. 1 What is GMSK ? GMSK stands for Gaussian Minimum Shift Keying. This is a modulation scheme in which the phase of the carrier is instantaneously varied by the \modulating" signal (i.e. the information to transmit). GMSK diiers from MSK (Minimum Shift Keying) in that a Gaussian Filter of an appropriate bandwidth (deened by the ...

the search for the self in becketts theatre: waiting for godot and endgame

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
