| 摘 要： | The sign algorithm has been extensively investigated for digital echo cancellation appfication and other adaptive filtering appfications. In this paper, we use the blind averaging Signregressor (SR) algorithm for adaptive multiuser detection. It is another least mean square (LMS) algorithm and eliminates the need for multiplication in the adaptive algorithm. The new algorithm not only reduces the calculation complexity but also has good convergence character. Simulations indicate that this algorithm can adapt to the changes of the environment quickly and improve the stability of the SIR.
