Two constructions for 16-QAM complementary sequence sets with non-power-of-two length

Complementary sequences with quadrature amplitude modulation (QAM) symbols have important applications in OFDM communication systems. The objective of this paper is to present two constructions of 16-QAM complementary sequence sets of size 4. The first construction generates four complementary sequences of length L = 2m− 1 + 2v, where m and v are two positive integers with 1 ≤ v ≤ m − 1. The second one leads to four complementary sequences of length L = 2m− 1 + 1. It turns out that the peak-to-mean envelope power ratios (PMEPRs) of constructed complementary sequence sets are upper bounded by 4.

Sets of complementary sequences

A set of complementary sequences is a set of sequences such that, for each nonzero offset, the out-of-phase aperiodic autocorrelations of all the sequences sum to zero. It is shown that the sequences from any coset of an (N, m) nondegenerate minimal linear cyclic code over GF(p) form a set of complex-valued complementary sequences of length N.
