Efficient Encoding/Decoding for Second-Order Spectral-Null Codes by Reducing Random Walks
Ching‐Nung Yang, Chih-Yang Chiu, Gen-Chin Wu · IEEE Transactions on Computers · 2010
Second-order spectral-null (2-OSN) codes are, in general, constructed from concatenating any codewords in 2-OSN code. Most 2-OSN codes adopt the Tallini-Bose random walk method in encoding and decoding, which exchanges two adjacent bits each time in a binary vector. In this brief contribution, we give a new implementation of the Tallini-Bose random walk method for 2-OSN codes which is shown by experiment to be faster.
