Method of transmitting n-bit information words, information transmission system for carrying out the method, and encoding device and decoding device for use in the information-transmission sys










Image Number 6 for United States Patent #4855742.

An information-transmission system including an encoder for converting n-bit information words (D7, . . . , D0) into transmitted m-bit code words (C10, . . . , C0), and a decoder which reconverts the received code words (C'10, . . . , C'0) into information words (D*7, . . . , D*0) corresponding to the original information words. For a first group the encoder converts a first portion (D7, . . . , D3) into a first portion of a code word, such portion comprising q bits (C10, . . . , C5) thereof; and converts a second portion (D2, . . . , D0) of the information word into a second portion of the code word, such portion comprising s bits (C4, . . . , C0) thereof. For a second group the encoder converts a first portion (D7, . . . , D3) into a second portion comprising q bits (C'5, . . . , C'0) of a code word, and converts a second portion (D2, . . . , D0) of the information word into a first portion comprising s-bits of (C'10, . . . , C'6) such code word. The decoder reconverts a received code word by converting the first portion of such code word (C'10, . . . , C'5) into the first portion (D*7, . . . , D*3) of the information word to be reconverted therefrom; and converts the second portion of such code word (C'4, . . . , C'0) into the second portion of such information word (D*2, . . . , D*0). The decoder converts a received code word in the second group of information words by converting the first portion of such code word (C'5, . . . , C'0) into the second portion (D*7, . . . , D*3) of the information word to be reconverted, and converts the second portion of such code word (C'10, . . . , C'6) into the first portion of such information word (D*2, . . . , D*0).
