Explore MATLAB source code curated for "调制仿真" with clean implementations, documentation, and examples.
Simulation of analog signal modulation techniques including DSB-SC, Bipolar Return-to-Zero, AMI, and CMI codes, with code implementation details for waveform generation and signal analysis.
This MATLAB-based program performs comprehensive modulation simulations for BPSK, QPSK, and 8PSK schemes, with modular architecture supporting easy extension to MPSK and MQAM. The implementation comprises three core components: phase.m handles pulse shaping using rectangular, raised cosine, or square-root raised cosine pulses; model.m serves as the main program executing constellation mapping, pulse shaping, and modulation; command.m provides spectral analysis visualization for performance verification.
