A Partial-Response Receiver for Miller-Squared Encoded Signals with Half the Usual Operating Speed

A new receiver for Miller-squared (M2) encoded signals is described that has a 50% lower operating speed than its predecessors, which reconstruct the encoded signal before decoding the original data. The reduction is achieved by using partial-response techniques to detect a linearly transformed and decimated version of the encoded signal, from which the original data can be recovered by means of a simple decoder. Simulations confirm the feasibility of this approach and indicate that the performance of the receiver improves upon that of its conventional counterpart under certain conditions.
