A signals reception chain including: 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, the channels being identical, at least one analog-digital converter that operates on 1 bit of the signals in phase or in opposite phase, on each of the channels, and a digital processor for processing the converted signals stemmed from the channels, and performing operations between the converted signals in phase or in opposite phase.
