Title:
METHOD AND APPARATUS FOR GENERATING PAIR OF ORTHOGONAL SETS WITH WIDE RANGE OF SPREADING FACTORS
Document Type and Number:
WIPO Patent Application WO/2013/085262
Kind Code:
A1
Abstract:
A method and apparatus that constructs a pair of orthogonal sets of codes with low values of inter-set correlation in overloaded spread spectrum systems is disclosed. The spreading factor of the generated sets can assume any value N for which a two level autocorrelation sequence of period N-1 exists. Thus, the method facilitates enhanced flexibility in the choice of processing gain of the system. The generated sets do not contain the codeword with single polarity.
