ABSTRACT:
In an adaptive CDMA receiver (20), a DS-SS received signal and a reference signal are equalized by minimizing the error between them the received signal includes a desired DS-SS communication signal comprising binary bits coded with spreading chip sequences. The received signal is sampled at a chip rate to produce sampled received signals which are correlated with each other. The received samples are de-correlated by employing an orthogonal transformation algorithm to provide de-correlated elements corresponding to the received samples. The equalization process is accelerated by minimizing the error based on the de-correlated elements.
