Data detection and decoding system and a method of detecting and decoding data
A data detection and decoding system in which a single parity bit added to the end of each code word by the encoder is used in the channel detector to improve the accuracy with which bit decisions are made in the channel detector. The bit estimates and the reliability estimates are then processed by...

| Summary: | A data detection and decoding system in which a single parity bit added to the end of each code word by the encoder is used in the channel detector to improve the accuracy with which bit decisions are made in the channel detector. The bit estimates and the reliability estimates are then processed by the decoder to recover the original input bits. By using single parity for this dual purpose in combination with a decoder that follows the channel detector and uses the bit estimates and reliability estimates to recover the original input bits, performance of the data detection and decoding system is greatly improved while also overcoming the disadvantages of known digital recording systems. |
