We propose an algorithm for joint channel estimation and detection in application to a practical scenario of detection of random access bursts in the W-CDMA UMTS system. The proposed algorithm is based on using the FFT algorithm for matched filtration and further signal processing with symbol rate sampling; as a result, it is well suited to implementation with modest DSP resources. We have performed simulation of the algorithm in different multiuser, multipath and frequency uncertainty environments; the simulation has shown high detection performance of the proposed algorithm.
