Method for processing a signal coming from a transmission channel, in particular a signal conveyed via power-line communication, and notably the estimation of the channel, and corresponding receiver

A method for processing a channel analog signal coming from a transmission channel, the method comprising:

• at least one detection phase for detecting a state of the transmission channel based on a channel digital signal from an analog/digital conversion of the channel analog signal to detect whether the transmission channel is, over an interval of time, at least one of linear and time invariant (LTI), and linear and cyclostationary.

A method for processing a channel analog signal from a transmission channel, the method comprising:

• converting the channel analog signal into a channel digital signal;
• and
• detecting a state of the transmission channel based on the channel digital signal to detect whether the transmission channel is, over an interval of time, at least one of linear and time invariant (LTI), and linear and cyclostationary.

A method for processing a power-line communication (PLC) analog signal from an electrical power line transmission channel, the method comprising:

• converting the PLC analog signal into a channel digital signal;
• and
• detecting a state of the electrical power line transmission channel based on the channel digital signal to detect whether the electrical power line transmission channel is, over an interval of time, at least one of linear and time invariant (LTI), and linear and cyclostationary.
