Document Type and Number:
Japanese Patent JP2876856
Kind Code:
B2
Abstract:
A method and apparatus of estimating a data sequence transmitted using a Viterbi algorithm, are disclosed. Sampled values of incoming data are acquired at a predetermined time interval into a memory. Subsequently, a plurality of sampled values are retrieved from the memory. Further, a plurality of receive signal replicas, which have been previously prepared and stored in another memory, are retrieved. A plurality of receive signal replicas are determined by multiplying the sampled values by the receive signal replica coefficients. Branch metrics are then determined using the sampled values of the incoming data and the receive signal replicas. A data sequence is estimated using the branch metrics according to the Viterbi algorithm.
