Method for estimating a cyclostationary transmission channel, and corresponding receiver

A method for processing an analog channel signal from a transmission channel, the analog channel signal conveying a plurality of frames, the transmission channel being linear and cyclostationary for a duration of at least one frame, the method comprising:

• converting of the analog channel signal into a digital channel signal;
• performing a plurality of channel estimations for the at least one frame based upon the digital channel signal to generate a sequence of N transfer functions of the transmission channel;
• each of the sequence of N transfer functions being respectively associated with N successive time slices;
• a duration of the N successive time slices being equal to or less than a cyclostationary period of the transmission channel;
• and
• decoding at least some symbols of the at least one frame using, for each of the at least some symbols, a transfer function associated with a successive time slice including a respective symbol.

A receiver comprising:

• an input stage to be coupled to a transmission channel and configured to receive an analog channel signal;
• a converter stage configured to convert the analog channel signal to a digital channel signal, the analog channel signal conveying a plurality of frames, the transmission channel being linear and cyclostationary for a duration of at least one frame;
• and
• a processor configured to
• perform a plurality of channel estimations for the at least one frame based upon the digital channel signal to generate a sequence of N transfer functions of the transmission channel,
• each of the sequence of N transfer functions being respectively associated with N successive time slices,

• decode at least some symbols of the at least one frame using, for each of the at least some symbols, a transfer function associated with a successive time slice including a respective symbol.
