<p>The present invention relates to spreading data of a plurality of digital communication channels having different data rates with code sequences having different lengths. The inventive circuit allows to use a single hardware unit for spreading communication channels having different data rates, e.g. in a CDMA telecommunications system. This is achieved by processing either a single 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 single hardware structure.</p> |
