Simulink Simulation of GMSK in GSM System

In GSM systems, wireless communication can be achieved through GMSK modulation and demodulation processing. GMSK (Gaussian Minimum Shift Keying) is an efficient modulation technique that converts digital signals into continuous analog signals and reconstructs digital signals from analog signals at the receiver. The Simulink simulation program enables performance evaluation of GMSK modulation/demodulation processing by implementing key components such as Gaussian filters, frequency modulators, and coherent demodulators. During simulation, various parameters like modulation index and bandwidth can be adjusted through parameter blocks to optimize system performance. Additionally, channel models can be incorporated using AWGN (Additive White Gaussian Noise) and fading blocks to simulate signal attenuation and noise effects during transmission. The simulation study of GMSK modulation/demodulation processing provides insights for understanding and improving the design and performance of wireless communication systems through systematic parameter analysis and BER (Bit Error Rate) performance evaluation.
