“…Orthogonal frequency-division multiplexing (OFDM) is a communication technique used in several wireless communication standards such as IEEE 802. 16 Mobile WiMAX. A major problem with OFDM is the large peak-to-mean envelope power ratio (PMEPR) of uncoded OFDM signals.…”

“…In [19], Yu and Gong proposed a method to construct near-complementary sequences, and gave several classes of near-complementary sequences with PMEPR≤ 4 by using shortened and extended Golay pairs as the seed pairs. In [16,18], the PMEPR bound of these near-complementary sequences were improved to asymptotically equivalent to 2, and new near-complementary sequences constructed by other seed pairs were also proposed.…”

We construct new complementary sequence sets of size 4, using a graphical description. We explain how the construction can be seen as a special case of a less explicit array construction by Parker and Riera and, at the same time, a generalization of another construction by the same authors. Some generalizations of the construction are also given, which are not in the construction of Parker and Riera. Lower bounds and upper bounds of the number of sequences in the constructions are analyzed.
