METHOD OF DETERMINING INFORMATION ELEMENT BOUNDARY, SYSTEM AND ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To realize an improved method of determining the boundary of an information element from a received signal. SOLUTION: Repetitively coded signals transmitted from satellites SV1-SV4 are received and modulated into information elements. A group of symbols forms one information element. Based on the received signals, a group of reference values (MA, SBS) is formed to form (CONV) at least one vector and the number of elements coincides with the number of symbols used for transmitting the information elements. Based on at least one vector, a determination vector is formed (AVG) and then a maximum element among the elements of the determination vector is detected (DET) to indicate the boundary of the information element with an index of that element.
