SPREADER FOR MULTIPLE DATA RATES

摘要

The present invention relates to spreading data of a plurality of digital communication channels having different data rates with code sequences havin g different lengths. The inventive circuit allows to use a single hardware uni t for spreading communication channels having different data rates, e.g. in a CDMA telecommunications system. This is achieved by processing either a sing le symbol and a corresponding long code in appropriate storage means for a channel with a lowest rate or to process a plurality of symbols and corresponding shorter code sequences of communication channels having higher data rates. Thus, a joint chip rate after spreading is obtained using a sing le hardware structure.
