Center node: "new constructions of complementary sequence pairs over 4 q qam"
  Abstract: The previous constructions of quadrature amplitude modulation (QAM) Golay complementary sequences (GCSs) were generalized as $4^q $-QAM GCSs of length $2^{m}$ by Li (the generalized cases I-III for $q\ge 2$) in 2010 and Liu (the generalized cases IV-V for $q\ge 3$) in 2013 respectively. Those sequences are represented as the weighted sum of $q$ quaternary standard GCSs. In this paper, we present two new constructions for $ 4^q $-QAM GCSs of length $2^{m}$, where the proposed sequences are also represented as the weighted sum of $q$ quaternary standard GCSs. It is shown that the generalized cases I-V are special cases of these two constructions. In particular, if $q$ is a composite number, a great number of new GCSs other than the sequences in the generalized cases I-V will arise. For example, in the case $q=4$, the number of new GCSs is seven times more than those in the generalized cases IV-V. In the case $q=6$, the ratio of the number of new GCSs and the generalized cases IV-V is greater than six and will increase in proportion with $m$. Moreover, our proof implies all the mentioned GCSs over QAM in this paper can be regarded as projections of Golay complementary arrays of size $2\times2\times\cdots\times2$.
