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

A system comprising a receiver) for receiving a repetition-coded signal that is modulated with information elements, in which signal a group of symbols has been used for transferring one information element, wherein the receiver comprises means for determining a boundary of the information element from the received signal, wherein the system further comprises at least:

• filtering means for forming reference values according to the received signal,
• vector-forming means for forming at least one vector of said reference values, in which said at least one vector the number of elements corresponds to the number of symbols used in the transmission of the information element,
• vector-processing means for forming the determination vector on the basis of said at least one vector,
• determination means for searching the greatest element of said terminating vector, wherein the index of the element is arranged to be used for indicating the boundary of the information element.

An electronic device comprising a receiver for receiving a repetition-coded signal that is modulated with information elements, in which signal a group of symbols has been used for transferring one information element, wherein the receiver comprises means for determining the boundary of the information element from the received signal, wherein the electronic device further comprises at least:

• filtering means for forming reference values on the basis of the received signal,
• vector-forming means for forming at least one vector of said reference values, in which said at least one vector the number of elements corresponds to the number of symbols used in the transmission of the information element,
• vector-processing means for forming the determination vector on the basis of said at least one vector,
• determination means for searching the greatest element of said terminating vector, wherein the index of the element is arranged to be used for indicating the boundary of the information element.
