COMMUNICATION METHOD, PULSE SYNCHRONIZATION CIRCUIT AND RECEIVER

摘要

PROBLEM TO BE SOLVED: To provide a receiver maintaining the state where pulses are synchronized, with a simple circuit, and also to provide a pulse synchronization circuit and a communication method used therefor.

SOLUTION: The receiver is provided with an integrator 202 for synchronization and a pulse synchronization correcting control unit 209. The integrator 202 receives a communication frame provided with a synchronizing pulse for representing data on the basis of the presence or absence of a pulse in a first channel and synchronizing the pulse position with a second channel different for the first channel, the channels each being assigned to each of time slots obtained in such a way that the pulse section of a pulse sequence of data representing data by the pulse sequence modulated by an on-off keying scheme is sub-divided into a plurality of time slots, and integrates the received frame for each of a standard period, a progress period and a delay period which are periods corresponding to the second channel. The unit 209 matches the pulse synchronization timing with an integration period in which integration value by the integrator 202 is the maximum.
