Design of LPI signals using optimal families of perfect polyphase sequences

In this paper, we discuss some conditions for LPI signals, and propose a system with multiple users requiring these LPI properties using the optimal families of polyphase sequences recently discovered by Park et. al. We discuss and prove the bound on the key space for candidates, and conclude that o...

Summary:In this paper, we discuss some conditions for LPI signals, and propose a system with multiple users requiring these LPI properties using the optimal families of polyphase sequences recently discovered by Park et. al. We discuss and prove the bound on the key space for candidates, and conclude that our system is more secure than those employing encrypted sequences using AES-128 against brute-force attack.
