ABSTRACT:
A sequence estimator for estimating a data sequence which is to be transmitted using a Viterbi processor, includes a register for storing, at a predetermined time interval, signals applied to the sequence estimator. A channel impulse response calculator is provided to receive the signals stored in the register which determine an estimated channel impulse response of each of possible transmitted data sequences. The sequence estimator further includes a branch metric calculator which determines a plurality of branch metrics using the receive signal, the possible transmitted data sequence and the estimated channel impulse response.
