Abstract:
1. A signals reception chain comprising: an input interface receiving a signal and transforming the received signal into at least two signals correlated in phase or in opposite phase, each of the correlated signals being distributed on at least one channel, an analog-digital converter, on each of the channels, that operates on 1 bit of a respective one of the correlated signals, wherein signals operated on by all analog-digital converts are in phase or in opposite phase, and a digital processor that processes signals from all of the analog-digital converters, wherein all the signals received from each of the analog-digital converts are in phase or in opposite phase, and said digital processor includes at least means for performing operations between said signals from each of the analog-digital converts, wherein the channels are identical from the input interface to the digital processor and include distinct electronic parts introducing uncorrelated noises onto each channel, and the means for performing operations includes at least one multiplier, or at least one adder when said signals received from each of the analog-digital converts are in phase, or at least one subtracter when said signals received from each of the analog-digital converts are in opposite phase, or said means for performing operations makes at least one linear combination or at least one equalization of said signals received from each of the analog-digital converts.
