  Complete complementary codes (CCCs) are highly valuable in the fields of
information security, radar and communication. The spectrally null constrained
(SNC) problem arises in radar and modern communication systems due to the
reservation or prohibition of specific spectrums from transmission. The
literature on SNC-CCCs is somewhat limited in comparison to the literature on
traditional CCCs. The main objective of this paper is to discover several
configurations of SNC-CCCs that possess more flexibility in their parameters.
The proposed construction utilised the existing CCCs and mutually orthogonal
sequences. The proposed construction can cover almost all lengths with the
smallest alphabets $\{-1,0,1\}$. Further, the idea of SNC-CCC is extended to
multiple SNC-CCC with an inter-set zero cross-correlation zone (ZCCZ). Based on
our construction, we can also control the correlation value outside the ZCCZ.
The beauty of the obtained codes have aperiodic and periodic inter-set ZCCZ and
low cross-correlation side-lobs.
