Wideband Code Division Multiple Access(CDMA) Simulator

The project should simulate the WCDMA air interface both uplink and downlink

according to standards defined by 3GPP.

The signal simulator should transmit data on aframe by frame basis through a time

varying channel, which is corrupted by multiple access interference.

Bit error rate should be investigated under different channel configurations as

well as performance due to error correction coding scheme.

The project should be implemented with a GUI application using Matlab.

Simulink should not be used.

**Background

**The gradual evolution from today's systems is driven by demand for capacity, which is requiredby the new and faster data based mobile services. WCDMA is the dominating3G technology, providing high data transmission rates, efficient apcket access, high service flexibility as well as support for future capacity and coverage enhancing technologies. WCDMA uses a new spectrum with a 5 MHZ carrier, providing 50 times higher data rate than in present GSM networks and 10 times higher than GPRS networks. WCDMA handles up to 2Mbps for local area acess or 384 Kbps for wide area access. A coming release will include enhancements up to more than 10 Mbps.

WCDMA is also known as UMTS and has been adopted as a standard by the ITU under the name IMT-2000 direct spread.
