Multirate scheme in WCDMA (Wideband Code Division Multiple Access) deals with how to multiplex several services with different rates and Quality of Service (QoS) in a flexible and efficient way
and is a distinct characteristic in the 3G mobile communication systems.Rate Matching Algorithm is the key algorithm in Multirate scheme.This paper
according to the latest WCDMA (FDD) multirate scheme of 3GPP(3G partnership project)
presents detailed comparison and analysis of rate matching algorithm in the uplink/downlink
and carries out some preliminary discussion about its possible improvement.
