Abstract
A device and method for generating a pseudo-orthogonal code for use in orthogonally spreading channel data in a CDMA mobile communications system. M orthogonal codes are selected from N orthogonal codes, for forming a pseudo-orthogonal codes, and the elements of the selected M orthogonal codes are sequentially interlaced to generate the pseudo-orthogonal code as a sequence of M×N elements.
