Hybrid receiver with learnable decider

A method for processing a signal, comprising:

• acquiring the signal by a receiver of a communication system;
• extracting a pilot signal based on the acquired signal, the pilot signal being indicative of at least one channel condition parameter of a communication channel over which the signal has been acquired;
• generating an equalized signal based on the acquired signal and the at least one channel condition parameter, the equalized signal being indicative of a modified acquired signal generated based on the at least one channel condition parameter;
• generating a first demapped signal based on the equalized signal;
• generating, using a first Neural Network (NN), a selection parameter based on the first demapped signal and the pilot signal;
• selectively employing, based on the selection parameter, a second NN for generating a second demapped signal based on the first demapped signal and the acquired signal;
• and
• decoding the second demapped signal using a decoder of the communication system.
