Abstract :
New polyphase sequences, named Px sequences, of a square integer length are found. Standard merit factors of polyphase Frank (1963), P1, P3, P4, Golomb and Chu (1972) sequences are compared with merit factors of Px sequences. It is found that Px sequences have better sidelobe-energy merit factor and not worse maximum-sidelobe merit factor in comparison to all mentioned analytically constructed sequences.
