Designing and Simulating Wireless Communication Systems Using MATLAB

This program can be executed directly to implement the following functionalities: Designing and simulating wireless communication systems using MATLAB software. The simulation configuration includes a single-tone audio signal as the source, Amplitude Shift Keying (ASK) as the modulation scheme, a multipath channel with 2 propagation paths, and Additive White Gaussian Noise (AWGN) as the channel impairment. Coherent demodulation is employed at the receiver end. The implementation generates performance curves showing the relationship between demodulator output characteristics and the Signal-to-Noise Ratio (SNR), providing clear insights into wireless communication system performance for future research reference. Key implementation aspects include: - Signal generation using MATLAB's waveform creation functions - ASK modulation implementation with digital carrier multiplication - Multipath channel modeling with delay profile simulation - AWGN addition using randn function for noise generation - Coherent detection with carrier recovery and correlation techniques - SNR variation through systematic noise power adjustment - Performance metric calculation and graphical plotting using MATLAB's plotting functions
