Abstract:
1. A method of generating a pair of orthogonal codesets with a spreading factor N for a direct sequence spread spectrum communication system, the method comprising: selecting a two-level autocorrelation sequence of a period of N−1, the two-level autocorrelation sequence comprising elements, each of which comprises a value of 1 or 0; obtaining binary sequences based on the two-level autocorrelation sequence; obtaining quasi-orthogonal codesets based on the two-level autocorrelation sequence and the binary sequences; and generating the pair of the orthogonal codesets based on the quasi-orthogonal codesets, wherein at least one of the selecting, the obtaining of the binary sequences, the obtaining of the quasi-orthogonal codesets, and the generating is performed by a processor.
