ABSTRACT:
An unequal error protection Reed-Muller code and method for designing a generator matrix and decoder. A conventional RM code is concatenated with the combination of itself and a subcode of itself. The new generator matrix is decomposed to include empty submatrices. The resulting generator matrix allows parallel decoding of separate portions of the received code word vectors.
