发明名称 Rate 4/5 trellis code for PR4 channels with improved error propagation
摘要 A digital communication apparatus transmits sectors of digital values that include error correction values used to detect and correct errors within the sector. Each sector consists of a number of blocks and the error correction values of each block are useful in correcting up to a maximum number of erroneous digital units in that block. The digital communication apparatus encodes the blocks of digital units to transmit them through a channel and then decodes the channel's representation of those encoded blocks, where the channel's representation occasionally contains burst errors. The encoding and decoding is performed in a manner that reduces the number of consecutive erroneous digital units caused by any one burst error to a number less than the number of blocks in a sector, ensuring that the error burst corrupts at most one digital unit in each block.
