Abstract:
A digital communication system, comprising:a transmitting apparatus including a pattern generator configured to generate a synchronizing pattern including at least one repetition of a first pattern of symbols and a second pattern of symbols having a reversed polarity from the first pattern, the synchronizing pattern arranged by a third pattern indicating positions and a number of repetitions of the first pattern and the second pattern, a frame generator configured to generate at least one frame including data to be transmitted and the synchronizing pattern, and a transmitter configured to transmit the at least one frame; and a receiving apparatus including a receiver configured to receive the at least one frame, a filter configured to filter the received at least one frame based on parts of the symbols in the first pattern and a period of time between each of the parts of the symbols, and a detector configured to detect a plurality of values for identifying the at least one frame based on delaying the filtered at least one frame and the third pattern.
