Abstract :
Tallini and Bose introduced a recursive method to construct second-order spectral- codes which result in short (information length 16) base optimal second-order spectral- codes that can be easily implemented either with table lookup or enumerative coding. In this paper, the extended base suboptimal second-order spectral- codes (17 information length 32) obtained from two short base codes by lookup table are used to reduce the overall code length.
