Experimental Investigation of the Performance of the WCDMA Link Based on Monte Carlo Simulation Using Vector Signal Transceiver VST 5644

WCDMA is wideband digital cellular technology used for third Generation (3G) cellular communication.
This paper evaluates experimentally the performance of wideband code division multiple access
(WCDMA) by using the Monte Carlo simulation based technique. The generated output of the WCDMA
link using VST 5644R is used to collect random samples of EVM at the different frequency bands
1800MHz and 2100 MHz at QAM and QPSK modulation schemes and then the link up time probability is
being calculated from the statistical data obtained experimentally from Vector Signal Transceiver. The
results obtained shows that WCDMA link based on QAM modulation out performs QPSK.
