Resource Overview
This project implements MATLAB simulation for demodulation and FM0 decoding in RFID reader receiver modules. The simulation includes: generating received signals containing tag information, performing coherent demodulation of ASK signals, implementing sampling decision for demodulated signals, and executing FM0 decoding. Simulation results demonstrate successful signal recovery matching the transmitted data, validating the demodulation and decoding algorithms.
Detailed Documentation
We conducted MATLAB simulations for the demodulation process and FM0 decoding in RFID reader receiver modules. First, we simulated the received signal at the reader containing embedded tag information using waveform generation functions. Second, we implemented coherent demodulation for the received ASK signal using carrier synchronization and mixing operations to accurately recover the baseband signal. Third, the demodulated signal underwent sampling decision processing with threshold detection, followed by FM0 decoding algorithm implementation that included symbol synchronization and Manchester code interpretation. The simulation results clearly demonstrate that the received signal matches the transmitted signal, validating the effectiveness of our demodulation and decoding methodology. Key functions used include digital filter design, correlation detection, and state machine implementation for decoding logic.
