Method for recovery of lost or corrupted data by use of turbo-codes, involves dividing vectors of input symbols in sub-vectors of certain symbols by serial or parallel-unit, where sub-vectors are inputted in time variant differentiator

摘要

The method involves dividing vectors (u) of input symbols in sub-vectors of certain symbols by serial or parallel-unit (S-P). The sub-vectors are inputted in parallel nonbinary time variant differentiator (D-F). An input sequence is multiplied with two multiplicative sequences. The input sequence is provided as a vector with length of certain symbols. Output signal of the differentiator is inputted in inter leaver and after that in an adding unit, which adds the output signals of the differentiator. Vectors (w) are inputted in a time variant nonbinary accumulator (AC).
