摘要
This paper presents a novel method to correlate Loosely Synchronized (LS) codes generated from mutually orthogonal Complementary Sets of Sequences (CSS). The proposed correlator significantly reduces the total number of multiplications and additions to be performed, in comparison with straightforward correlators. This fast correlator, together with the interference free window that LS codes exhibit, make them a good choice for next generation of Wireless communications.
