摘要: Orthogonal codes of variable lengths are essential for multirate services in the Third-Generation Partnership Project (3GPP). We propose an alternative to Walsh functions spreading codes. There three important points. First, we design orthogonal code constant length by mapping points a set finite projective planes chips high/low amplitudes. Second, develop using multiple layers recursion. Last, compare and contrast proposed technique with terms ease synchronization, blind-rate detection wideband characteristics.
