Method of identifying data coded by PPM modulation, receiver for this method

摘要

The method involves constructing a chronological series of arrival times of impulsions or a block of successive impulsions contained in a received signal. Resemblance value is calculated between the series and a predetermined chronological sequence of arrival times coding data for temporary lags between the series and the sequence, where the value represents correlation between the series and the sequence for the given temporary lag. The data is identified in the series, if the value for one of lag exceeds a predetermined threshold. An independent claim is also included for a receiver for receiving a signal coded by a pulse position modulation.
