Title:
9B/10B ENCODING AND DECODING METHOD SUITABLE FOR LOW-PASS AND BANDPASS CHANNELS
Document Type and Number:
WIPO Patent Application WO/2023/165289
Kind Code:
A1
Abstract:
Disclosed in the present invention is a 9B/10B encoding method suitable for low-pass and bandpass channels, used for encoding a 9-bit source sequence set into a 10-bit target sequence set. The 10-bit target sequence set does not comprise balanced sequences "1010101010" and "0101010101". The 9-bit source sequence set comprises a first type of 9-bit source sequence set, a second type of 9-bit source sequence set, and a third type of 9-bit source sequence set. The first type of 9-bit source sequence set only comprises 9-bit source sequences of which the difference valued are 1 and -1, and after 1-bit data "0" or "1" is inserted into a same position of each sequence in the first type of 9-bit source sequence set, each sequence in the first type of 9-bit source sequence set is encoded into a 10-bit target balanced sequence. The second type of 9-bit source sequence set alternatively only comprises the 9-bit source sequences of which the difference value is 3 or only comprises the 9-bit source sequences of which the difference value is -3, and the 1-bit data "0" or "1" is inserted into each sequence in the second type of 9-bit source sequence set, and then each sequence in the second type of 9-bit source sequence set is encoded into a pair of 10-bit target unbalanced sequences of which the difference values are 2 and -2.
