Method and apparatus for systematic encoding of data in error correction coding using trigonometric factorization of generator matrix

摘要

The systematic encoder 300 that stably transmits the source data block (SDB) is an external transformation matrix and inner transformation matrix is composed for The inner encoder 301 receives the SDB and generates an output constraint block (OCB) 312 as an image of the SDB under the inverse of the submatrix of the inner transform matrix. An outer encoder 302 receives a fixed data block (FDB) 313 and an OCB and generates a transform output block (TOB) 315 as a phase of a transform input block (TIB) 314 under the outer transform matrix. The TIB transparently includes the FDB in a sub-block of the TIB, and the TOB transparently includes the OCB in the sub-block of the TOB. The inner encoder receives the TOB and generates a transmit code block (TCB), which includes the SDB transparently in sub-blocks therein.
