Abstract :
Quadriphase E-sequences are discussed. There are 512 quadriphase E-sequences of length 8. Among the 512 quadriphase E-sequences of length 8, 256 quadnphase E-sequences of length 8 have a nice property that each sequence composes a couple of autocomplementay sequences with its latter-half-inversed sequence. From the 256 quadriphase E-sequences of length 8, a class of zero-correlation-zone sequences (ZCZ sequences) can be obtained. The rehtionshzp between the quadriphase Esequences of length 8 and the quadriphase block code of wordlength 8 with the hyper polihedron Euclid distanse property is also discussed.
