An apparatus generates a statistical class sequence model called A class bi-multigram model from input training strings of discrete-valued units, where bigram dependencies are assumed between adjacent variable length sequences of maximum length N units, and where class labels are assigned to the sequences. The number of times all sequences of units occur are counted, as well as the number of times all pairs of sequences of units co-occur in the input training strings. An initial bigram probability distribution of all the pairs of sequences is computed as the number of times the two sequences co-occur, divided by the number of times the first sequence occurs in the input training string. Then, the input sequences are classified into a pre-specified desired number of classes. Further, an estimate of the bigram probability distribution of the sequences is calculated by using an EM algorithm to maximize the likelihood of the input training string computed with the input probability distributions. The above processes are then iteratively performed to generate statistical class sequence model.

A signal processor performs error correction on data which has been subjected to predetermined signal processing, for each predetermined block unit, by an error correction block, in parallel with an operation of sequentially storing the data in a cache memory. Then, error detection is performed on the data for each predetermined block unit by a descrambling/error detection block, and the data is stored in a buffer memory. Based on the results of the error detection and the error correction, when there exists some error in the data, the data with the error, which is stored in the buffer memory, is read out to be subjected to error correction again. When there is no error, the data corresponding to one block and stored in the buffer memory is transmitted to a host computer without performing error correction again.
