Novel Construction of Distinct Perfect Polyphase Sequences with Large Family Size

In a wireless communication system, sequences with impulsive periodic autocorrelation correlation, known as perfect sequences, are widely applied to, e.g., such sequences can be made use of as synchronous signals. In this paper, based on interleaving technique, a novel construction of distinct perfect polyphase sequences (PSs) is presented. The proposed perfect PSs possess the same phase alphabet size and sequence length as Frank perfect PSs, however, the former includes the latter as a special case and its family size is much larger than the latter´s.
