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. Figure 1
