Day by day, new coding schemes are being developed to adequate with the requirements of the present technological issues. In some cases, the practical implementation of these schemes involvesa great amount of operations and/or signal processing. In order to attain a good performance with the minimum requirements, efficient algorithms are also required to process the coding. In the last years, a new kind of complementary sequences known as Generalized Pairwise Complementary sequences have been proposed, which allows to encode multiuser systems with a high noise immunity. In this way, recently, an efficient algorithm to generate and correlate a pair of these sequences was developed. Although that proposal was an advance, it involves an important amount of operations, making it unsuitable for platforms of reduced resources. In the present workis proposed a generator and correlator for GPC sequences that optimizes the architectures. Additionally, the proposed architectures make it possible to process the whole set of GPC with lower amount of operations than the other efficient algorithms. The proposal is analytically demonstrated and a comparison with the previous proposal is conducted to evaluate the obtained improvement.
