wo former guest researchers at NIST, Maarit Melvasalo, from VTT, Finland, and Tommi Makelainen from Nokia Research Center, Finland, built a simulation of the 3GPP FDD proposal for 3G wireless. The simulation can run on Simulink or as a stand alone C-coded program. It includes the channel encoding, interleaving, rate matching, modulation, spreading(channelization), a channel model, a RAKE receiver, and the corresponding decoding functions. Both the downlink and uplink have been modelled.
