Pydemod

Pydemod is a set of Python libraries and tools for demodulating radio signals. It does not mean to compete with full-featured packages such as GNU Radio. Instead, it strives to allow radio enthusiasts to gain hands-on experience with modulation schemes.

Pydemod relies on NumPy/SciPy.

Currently, the released modules include:

• physical layer:
• phase demodulation (naïve)
• Manchester decoding
• basic logical levels (TTL-like) decoding and clock synchronization
• data link layer:
• synchronization and error detection for polynomial codes
• full implementation of RDS and AMSS codes
• CRC calculation
• application layer:
• functional AMSS decoder
• functional TFA temperature & humidity sensor decoder (should work for other Instant Transmission IT+ 868 MHz systems, such as LaCrosse ones)
