Open Implementation of Patented Algorithm (Japan Patent)

This repository provides an open implementation of the "Base Extraction Division Minimum Method," which is registered as a patent in Japan.

• This implementation is intended for research, verification, and evaluation purposes.
• Commercial use or redistribution requires obtaining a license (see below).

Features

• Quantitative pattern extraction
• Quantitative periodicity calculation
• Quantitative continuity calculation
• Multiplexing communication using shorter sequences than M-sequences and only 1-bit quantization.However, synchronization is required, randomness is not guaranteed, and signal-to-noise ratio (SNR) is not improved.

Demo

By running pattern_demo.ipynb and communication_demo.ipynb, you can obtain simple sample results:

Easy explanation is in doc.
