GMSK Modulation

This article introduces the simulation implementation of a GMSK transmission system. GMSK (Gaussian Minimum Shift Keying) is a modulation technique commonly used in digital communication systems. We will comprehensively discuss various aspects of GMSK transmission systems, including their underlying principles, technical specifications, and implementation methodologies. For simulating the GMSK transmission system, we employ MATLAB software and validate the simulation accuracy through experimental results. The implementation involves key steps such as Gaussian filtering of the input data stream, modulation using frequency shift keying with minimal phase transitions, and demodulation through coherent detection algorithms. Critical MATLAB functions include gmskmod for modulation, gmskdemod for demodulation, and built-in visualization tools for analyzing spectral characteristics and bit error rate performance. The objective is to provide readers with a thorough understanding of GMSK transmission systems and deepen their knowledge of modulation techniques in digital communications.
