Complementary sets of sequences (CSS) are widely used in communications field due to their good correlation properties. The use of multilevel CSS reduces the binary CSS limitations in length and number of sequences per set, giving more flexibility in their applications, but with a higher computational complexity in the implementation of the generation and/or correlation algorithms. Although efficient...
Complementary sets of sequences (CSS) are used extensively in many applications, as channel estimation and synchronization preamble or as a basic block for the generation of generalized orthogonal (GO) sequences. Nevertheless, binary CSS exist for very limited lengths, while for multilevel CSS there are fewer limitations in the sequence length. This paper presents two modular architectures for the...
