Abstract :
Perfect sequences have wide application fields, including spread spectrum communication, synchronization techniques, channel estimation, and cell search. In this letter, two kinds of (almost) perfect Gaussian integer sequences of length N=2 (mod4) and N=0 (mod4) are proposed and constructed by complex transformations and interleaving techniques, using the perfect Gaussian integer sequences of odd length as the base sequences.
