ABSTRACT:
Segregation of redundant control bits in an ECC permuted, systematic modulation code. Appropriately encoding of user information via combined modulation and RS (Reed-Solomon) encoding ensures segregation of scrambled user information, modulation redundancy bits, and RS redundancy bits in such a way that each of the components thereof are segregated and stored within any desirable digital information memory storage device. By providing this segregated capability, when accessing a portion of a RS codeword from the memory, an entire RS codeword need not be read from the memory. In fact, only the particular field (or bits) needs to be accessed to perform correction thereon. This segregation provides for a reduction in the hardware complexity of translation between user information and a modulation codeword. Also, this segregation provides for the ability to perform correction of only one of the scrambled user information, the modulation redundancy bits, or the RS redundancy bits.
