MATLAB Assignment: FM Signal Generation, Noise, Filtering, SNR

This MATLAB assignment focuses on the analysis of frequency modulated (FM) signals within a communication system. The objective is to generate an FM signal, introduce noise, apply filtering techniques, and then demodulate the signal. The solution involves the implementation of system modeling and simulation using MATLAB, including generating both the message and carrier signals. The assignment details the process of modulating the message signal, generating random noise based on unit variance, and analyzing the effects of noise on the signal. The performance of the communication system is evaluated by computing the signal-to-noise ratio (SNR) at the receiver. The solution also explores the impact of different modulation schemes and filter designs on the overall system performance. The report provides a comprehensive analysis of the FM modulation process, discussing the effects of noise and interference, and the use of filters to improve signal quality. The findings include phasor representations, modulator code, and channel filtering effects, alongside a discussion of the performance metrics and the implications of various design choices, such as the selection of filter bandwidth and the impact of the modulation index. The assignment concludes with a discussion on the benefits of FM and its common applications.
