Bhashyam, "Channel Estimation for Multirate DS-CDMA Systems," 2000.https://hdl.handle.net/1911/20311Conference paperThe problem of channel estimation for multiple data rate Direct-Sequence Code-Division Multiple-Acess (DS-CDMA) systems is addressed. The derived algorithms are suitable for both variable chipping rate and/or variable spreading multirate systems. Furthermore, methods for uplink and downlink channel estimation are investigated. It is observed that direct exploitation of the multirate nature of the signal yields improved performance. The algorithms are evaluated via simulation.engchannel estimationDS-CDMAConference paperchannel estimationDS-CDMA
