Abstract:
A device for transmitting digital data, representing a physical quantity, comprised of:a selector that selects certain couples of digital data which follow each other;a mapper that maps, according to a set of predetermined rules, each selected digital data couple to an amplitude couple; anda transmitter that transmits a signal in quadrature having a first component and a second component, said first and second components being respectively modified by first and second amplitudes of the amplitude couples, said set of predetermined rules including at least a first rule according to which, when an estimated probability that two amplitude couples are confused after the said transmission is greater than a first predetermined value, then the digital data couples corresponding to said two amplitude couples have first or second digital data items having a same value;wherein a component couple transmitted by the transmitter being received, is possibly affected by errors, by a receiver.
