In a spread spectrum digital radiocommunication receiver, a first estimate
of a symbol transmitted by a sender is calculated by applying to a radio
signal received a processing taking into account a number N of
propagation paths from the sender, a parameter of reliability of the
first estimate is evaluated, and when the reliability parameter evaluated
does not satisfy a confidence criterion, a second estimate of the symbol
is calculated by taking into account at least one (N+1)-th propagation
path from the sender in the processing applied to the radio signal
received.
