In the last decades, ranging systems have benefited from advances in the wireless communication field, as multiple access techniques or near-far mitigation algorithms. In CDMA- based (Code-Division Multiple-Access) ranging systems, the properties of the spreading sequence used play a key role on the development of high-precision ranging measurements. This thesis proposes novel efficient generation/correlation architectures of Complement- ary Sets of Sequences (CSS) and sequences derived from them, as Loosely Synchronized (LS) and Generalized Pairwise Complementary (GPC) sequences. We consider the term efficient applicable whether the proposed architectures requires less operations per input sample in comparison with a straighforward implementation (a Tapped-Delay Line implementation). The contributions of the thesis can be divided into two stages: Firstly, ... toggle 8 keywords
