ABSTRACT:
The present invention is directed to a detector circuit for detecting a binary data sequence from an input sequence of data. The detector circuit comprises a storage device for storing a plurality of values which correspond to the squared errors computed between all possible input values to the circuit and all possible noiseless responses. The storage device outputs certain of the stored values in response to the input sequence of data. The detector circuit also comprises a Viterbi circuit responsive to the storage device. The Viterbi circuit computes a binary decision output from the outputted stored values. The present invention is also directed to a method for detecting a binary data sequence from an input sequence of data.
