GMSK Modulation, Demodulation, and Bit Error Rate Implementation

In this program, I have meticulously implemented comprehensive functionality for GMSK modulation, demodulation, and bit error rate analysis. The implementation utilizes sophisticated signal processing techniques and optimized algorithms to ensure accurate performance in digital communication scenarios. The GMSK modulation component employs Gaussian filtering with BT product optimization to achieve superior spectral efficiency while maintaining constant envelope properties. The demodulation module implements coherent detection using Viterbi algorithm for optimal sequence estimation, significantly reducing inter-symbol interference. For bit error rate analysis, the program incorporates Monte Carlo simulation methods with configurable signal-to-noise ratio parameters. The implementation includes error counting mechanisms and statistical analysis tools to evaluate system performance under various channel conditions. Extensive testing and debugging have been conducted to validate the program's robustness across different operational scenarios. The code architecture features modular design with clear separation between modulation, demodulation, and BER calculation components, facilitating easy maintenance and performance optimization. Throughout the development process, significant effort has been invested in ensuring code accuracy, computational efficiency, and reliability, making this implementation suitable for both educational and research applications in digital communications.
