Query: A Direct Construction of GCP and Binary CCC of Length Non Power of Two   Golay complementary pairs (GCPs) and complete complementary codes (CCCs) have
found a wide range of practical applications in coding, signal processing and
wireless communication due to their ideal correlation properties. In fact,
binary CCCs have special advantages in spread spectrum communication due to
their simple modulo-2 arithmetic operation, modulation and correlation
simplicity, but they are limited in length. In this paper, we present a direct
construction of GCPs, mutually orthogonal complementary sets (MOCSs) and binary
CCCs of non-power of two lengths to widen their application in the recent
field. First, a generalised Boolean function (GBF) based truncation technique
has been used to construct GCPs of non-power of two lengths. Then Complementary
sets (CSs) and MOCSs of lengths of the form $2^{m-1}+2^{m-3}$ ($m \geq 5$) and
$2^{m-1}+2^{m-2}+2^{m-4}$ ($m \geq 6$) are generated by GBFs. Finally, binary
CCCs with desired lengths are constructed using the union of MOCSs. The row and
column sequence peak to mean envelope power ratio (PMEPR) has been investigated
and compared with existing work. The column sequence PMEPR of resultant CCCs
can be effectively upper bounded by $2$.
