ABSTRACT:
A method of regenerating data convolutes plural data using maximal-sequence codes phase shifted by individual quantities and writes the convoluted data into a cyclic memory. A data regeneration apparatus reads out a desired data from the cyclic memory using a corresponding maximal-sequence code. Another method of regenerating data convolutes plural data using sequence codes for which are obtained weighting factors and maximal-sequence codes phase shifted by individual quantities and writes the convoluted data into a cyclic memory. Another data regeneration apparatus reads out a desired data from the cyclic memory using a corresponding maximal-sequence code. Still another method of regenerating data method convolutes plural data using maximal-sequence codes phase shifted by individual quantities and writes the convoluted data into a cyclic memory. Still another data regeneration apparatus reads out desired data from the cyclic memory using sequence codes which are obtained by weighting factors and maximal-sequence codes phase shifted quantities by individual.
