Based On TMS320C6000 Dspchipwcdma Rake Receiver Realization

In the system of WCDMA, each user all uses the same frequency resources in the identical time to transmit the data, therefore has the same frequency disturbance problem; moreover, as a result of the multi- ways question existence, causing with the signal between the disturbance is also very serious. The traditional receiver takes the same frequency unwanted signal noise processing, but the receive effect is not very good. Rake which concept proposed changed the traditional data receive way: rake is regarded as the same frequency and the multi- ways signal data message itself a part, selects the method which multi user detects to go to the better synthesis effective data. Rake The receiver is the influence CDMA System receive effect important attribute. This article uses TI TMS320C62XSeries chip realization WCDMA Rake The receiver, and is right Rake The algorithm has carried on the thorough discussion, proved through the simulation and the test data: Uses and improves Rake The receiver can cause entire WCDMA The system obtains the better data receive effect.
