| 摘要 |
<p>The invention relates to a method for decoding data signals spread using Walsh sequences and to a corresponding decoder. The invention evaluates correlation functions of time-delayed data signals in order to distinguish whether a received spread data signal belongs to the same transmission channel or constitutes an asynchronously arriving extraneous signal or another interference signal. The decoder comprises a special decision-making module for evaluating the amplitude profile of the correlation functions. The invention can be integrated, as a hardware or software module, in existing CDMA transmission systems or can be used for faster transmission in future mobile radio generations.</p> |
