Abstract

Code Division Multiple Access (CDMA) has been used in cellular communications area, e.g., in the second generation mobile phones since early 1990’s. Wideband CDMA (WCDMA) is a newer and faster radio technology used in the third generation mobile phones. A Frequency Division Duplexing WCDMA (FDD-WCDMA) has already been employed. In the FDD mode WCDMA, the system uses different frequency bands for the Uplink and Downlink communications. In the Time Division Duplexing WCDMA (TDD-WCDMA) mode, the system uses different time slots but the Uplink and Downlink share the common frequency band. In the TDD-WCDMA, there are two options for bandwidth: 1.28MHz and 3.84MHz. Users can send their data by spreading the data parts in a slot. The Midamble part in a slot is used for channel estimation and the guard part in a slot is for multipath interference suppression. In this work, error control codings, channel estimation, multistage multiuser detection, and power control are studied for the TDD-WCDMA communications.
