초록 ▼

Channel encoded data (for example run length limited encoded data) is further encoded in accordance with a shift correction code prior to transmission. Upon reception, forward and backward shift errors present in the received channel encoded data are corrected by a shift correction decoder. The shift error correction is accomplished using a code, such as (for example) a BCH code over GF(p) or a negacyclic code, which treats each received symbol as a vector having p states. For a single shift error correction, p=3 and there are three states (forward shift, backward shift, no shift). In one embodiment, conventional error correction codewords which encode the user data may be interleaved within successive shift correction codewords prior to channel encoding, thereby enabling the error correction system to easily handle a high rate of randomly distributed shift errors (which otherwise would result in a high rate of short error bursts that exceed the capacity of the block error correction code).

대표청구항 ▼

A process for correcting shift errors in a block of run length limited (RLL) channel encoded data in a channel, wherein shift errors cause as many as t separation bits in said block of channel encoded data each to be shifted by as many as (p-1)/2 bit positions, wherein p is at least 3 (one bit forward, one bit back, no shift), said process comprising: run length limited encoding a set of digital symbols to generate a block of RLL data, converting each run length in said RLL data block to an element of a Galois field related to GF(pm) so as to form a block of Galois field symbols; encoding said Galois field symbol block in accordance with a first code related to GF(pm) so as to compute a set of check symbols from said Galois field; and RLL encoding said set of check symbols from said Galois field to produce a check block of RLL data and appending said check block to said RLL data block to form a shift correction RLL data block, and transmitting said shift correction RLL data block to said channel.
