Abstract :
UMTS is the European standard of the third generation of mobile communications and its air interface is called WCDMA. In this paper a simple WCDMA system in downlink and FDD mode is simulated and results are presented. The simulation that is an execution, apart from physical layer functions as layer 1, includes data modulation, spreading multipath channel, AWGN noise, data demodulation, despreading and Rake receiver. It is obvious that transmission methods of data correspond to WCDMA standards. In other words, frames and slots structure, data symbols setting and required parameters follow the defined standards.
