#CMT# #/CMT# The method involves releasing two distinct scrambling (20, 21) of data to provide two sets of scrambled data. Inverse Fourier transform of the scrambled data are determined, and amplitude dynamics of each data are determined after determining the inverse Fourier transform. One of the set of scrambled data is selected from the two sets of the scrambled data using a selection module (26), where the selected set of scrambled data is intended to transmit and present amplitude dynamic compatible with maximum dynamic authorized by an assembly formed by digital-to-analog converter and an amplifier. #CMT# : #/CMT# An independent claim is also included for a system for transmitting data from a unit towards another unit. #CMT#USE : #/CMT# Method for transmitting data in a rough environment such as oil well, from a unit, located at the predetermined depth, towards another unit, located at a surface of the well in an aggressive environment such as high temperature environment, corrosive gas environment, confinement environment and limited guiding environment, via a cable e.g. hepta-cable and coaxial cable, forming a propagation channel. #CMT#ADVANTAGE : #/CMT# The set of scrambled data, intended to transmit and present the amplitude dynamic compatible with the maximum dynamic authorized by the assembly, is selected, thus decreasing the probability that the saturation of the assembly of the converter and amplifier do not occur, and hence transmitting data from the unit located towards another unit in a simple manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block diagram of modules implementing the stages for transmitting data.'(Drawing includes non-English language text)' 7 : Serializer 20, 21 : Distinct scrambling 22, 23 : Mapping modules 24 : Combination module 26 : Selection module. |
