Abstract:
1. Method for correcting the duty cycle of a received signal, wherein said signal comprises a synchronization field ( 22 ), said synchronization field comprising a number of cycles of a high state followed by a low state or vice versa, said method comprising the steps of: transforming said signal into a first block wave ( oversampling said first block wave with a sample signal ( deriving from at least a part of said first block wave, the duty cycle of said first block wave by counting the number of samples, obtained by oversampling and corresponding to a high state and the number of samples, obtained by oversampling and corresponding to a low state in one or more cycles of the incoming signal and, producing a second block wave ( after oversampling said first block wave ( calculating from said numbers n and m, the duty cycle of said first block wave ( if n<m, delaying each high to low transition relative to the previous low to high transition in at least a part of said first block wave ( if n>m, delaying each low to high transition relative to the previous high to low transition in at least a part of said first block wave (
