Explore MATLAB source code curated for "AMI编码" with clean implementations, documentation, and examples.
This is a self-developed MATLAB code for AMI line coding implementation. Please carefully review the code before use, and if any errors are found, kindly provide corrections. The implementation demonstrates binary-to-AMI signal conversion with polarity alternation logic.
A. Generate a 1000-length binary random sequence with P(0)=0.8 and P(1)=0.2; B. Apply Return-to-Zero AMI encoding (50% pulse width, 8x symbol rate sampling), plot waveforms for first 20 symbols; C. Implement HDB3 coding and plot corresponding waveforms; D. Switch to Miller coding and visualize waveforms; E. Perform power spectrum estimation for all 1000 symbols; F. Observe AMI power spectrum variations with changing source probabilities. Includes MATLAB implementation details for random sequence generation, coding algorithms, and spectral analysis.
