| 摘要 |
The present invention relates to data communication, distance measuring, and location tracking using TDC-multi pulse position modulation (PPM). According to the embodiment of the present invention, high speed data communication using TDC-multi pulse position modulation is provided. The position of data pulse encoded by the PPM is measured using the TDC. A TDC-PPM demodulator is provided. [Reference numerals] (330a) TDC_multi PPM demodulator; (330b) Device for measuring the distance/device for tracking the location; (AA) Digital code data communication; (BB) Digital code distance, measurement |
