System Simulation of PPM Modulation with Performance Analysis

This project implements a comprehensive PPM modulation system simulation using MATLAB, focusing on bit error rate (BER) analysis under Gaussian channel conditions. The simulation replicates real-world communication scenarios by modeling additive white Gaussian noise (AWGN) channels, enabling quantitative performance assessment of PPM schemes. Key implementation aspects include: - Generation of PPM symbols through pulse positioning algorithms with time-slot mapping - AWGN channel integration using randn() function for noise modeling - BER calculation via statistical comparison between transmitted and received symbols - Parameter optimization interface for adjusting signal-to-noise ratio (SNR) levels The simulation framework allows dynamic parameter tuning (e.g., SNR variations) to observe corresponding BER fluctuations, providing valuable insights for communication system design and optimization. This experimental approach demonstrates practical methodology for evaluating modulation robustness and transmission efficiency in noise-affected environments.
