Abstract
In a communication network, a method for channel quality estimation, without the need for a reference (uncorrupted) signal, comprises the steps of: processing a received signal utilizing a non-redundant error correction scheme to observe at least one symbol; producing an error signal in response to the observation; and counting a quantity of the error signal during a predetermined time interval to provide a symbol error count. A device for channel quality estimation, without the need for a reference (uncorrupted) signal, is also described.
