<p>This invention discloses a forming method and a transforming method of orthogonal code group applied in any code division multiple access system, spread spectrum system and digital communication system. The method makes the orthogonal code group is formed from a nonzero real number and complex number sequence, with any length, by orthogonal rotation. The method also makes multi-groups of orthogonal code, which are got by orthogonal rotating transformation from any code group, with real number and complex number. The multi-groups of orthogonal code keep substantially consistent characteristics with the original code group, and every code is orthogonal with each other before and after transformation.</p> |
