WCDMAsim™
WCDMAsim™ is a Matlab™ based, physical layer simulation of a 3G wireless system that conforms to the WCDMA standard. This simulator emulates the behavior of WCDMA base and mobile stations in specular multipath fading environments. WCDMAsim™ was specifically developed to provide the 3G wireless industry with a suite of simulation tools that conform to the European Telecommunication Standards Institute (ETSI) developed standards for the WCDMA air interface.
WCDMAsim™ provides a technically accurate and detailed emulation of a WCDMA system. Users can simulate a base station that employs Space Time Transmit Diversity (STTD) in the downlink and a mobile terminal that uses up to six Dedicated Physical Data Channels (DPDCH) in the uplink, a feature that mobile terminals use to support the transmission of broadband data. Users can also configure the base station by selecting the number of channels, the types of channels (data channels, control channels, pilot channels, etc.), and the specific format for each channel.
One unique feature of WCDMAsim™ is its ability to produce more than just average Bit Error Rate (BER) statistics. Rather, this simulator supplies users with an error length sequence that contains not only the number of errors but also the location of each error in the data sequence. With this additional level of detail, researchers can compute high order BER statistics and determine the clustering properties of error events. This information is crucial for the development of computationally efficient simulations, such as Hidden Markov Model (HMM) simulations of large-scale wireless networks.
