Abstract

PURPOSE:To make a decision on a data block with accuracy at any time without using an additional channel by increasing or decreasing the frequency of data transmission in accordance with the appearance state of a transmission pattern. CONSTITUTION:When data 13 in the same pattern with a flag appear in a data block, data 16 in the pattern are transmitted and then data 17 in the same pattern are sent again before the next data. At a reception side, when the pattern of data 13 is received, a stand-by state is set until the next data are received; when the next data are in the pattern of data 13, they are regarded as data and when the next data differ in pattern from data 13 or when the next data are not received within a certain time, they are regarded as the flag.
