Non-contiguous Carrier Interferometry (NC-CI) signature waveforms have been proposed for Dynamic Spectrum Access (DSA) and Cognitive Radio (CR) system in the literature. Walsh-Hadamard (WH) codes cannot ensure orthogonality for non-contiguous carrier allocation, when the number of non-contiguous carrier is not a multiple of 4. In literature, NC-CI and binary orthogonal codes of any code length are...
