Analysis and equalization of delay in asynchronous CDMA system using unscented filtering

In this paper, we present analysis and equalization for asynchronous received signals in a code-division- multiple-access (CDMA) system. The equalization is performed using the unscented filer (UF). This equalization helps the multiuser detector to estimate the desired signal in asynchronous system without the need of estimating the delays of the asynchronous users. Simulations are presented to show the performance of the equalizer.
