  • Method and apparatus for generating preamble using chaotic sequence
    Patent number: 7457291
    Abstract: A preamble generating method which includes computing (N) chaotic samples; transforming the (N) chaotic samples into (N) binary values of certain bits, respectively, and computing a chaotic sequence bit successively using the (N) binary values; and generating a preamble based on the chaotic sequence bit. By using the sequence bit from the chaotic samples, a plurality of preambles with optimum auto-correlation and cross-correlation properties is generated.
    Type: Grant

    Date of Patent: November 25, 2008
    Assignee: Institute of Radio Engineering and Electronics of RAS
    Inventors: Ye-hoon Lee, Yong-suk Kim, Dmitriev Alexandre, Starkov Sergey
