Brief description of the demodulation of at least one frame constituted by a succession of bits according to the codes manchester code.

摘要

The present invention relates to a process for the demodulation of at least one frame received, the frame being formed by a succession of coded bits according to the manchester code. The method comprises the steps of: - generation of an interruption at least at each appearance of an edge of the frame bits, - determination of the time between each interruption from at least a first counter, - reinitialization of the demodulation of the frame as soon as one of the determined time is less than a first predetermined value or greater than a second predetermined value, the first and second predetermined value is dependent on the duration of a bit encoded in accordance with the code, - demodulation (e222, e223, for each predetermined time, if the determined time is greater than the first predetermined value, and is less than the second predetermined value, of at least a binary value of the frame on the basis of the determined time.
