Abstract :
A blind channel identification scheme based on oversampling the channel output and employing a (discrete) cyclic correlation function similar to Gardner (1991) is proposed. It is shown that the known results on blind identifiability follow directly. Further, this connection suggests a new and efficient time-domain algorithm for blind channel identification that is applied to some representative examples.<>
