Method for determining a boundary of an information element, a system, and an electronic device

摘要

The invention relates to a method for determining a boundary of an information element, in which repetition-coded signal transmitted by satellites is received, which signal is modulated with information elements. A group of symbols forms one information element. In the method a group of reference values are formed on the basis of the received signal. Of these reference values at least one vector is formed wherein the number of the elements corresponds to the number of symbols used in the transmission of the information element. A determination vector is formed on the basis of said at least one vector, whereafter the greatest of the elements of said determination vector is searched, wherein the index of said element indicates the boundary of the information element.
