A performance evaluation of SCA-FDMA implementation on LabVIEW platform

Abstract

This paper discusses about a modelling, implementation and performances evaluation of physical layer of single carrier frequency division multiple access (SC-FDMA). They are done on LabVIEW model-based platform. The SC-FDMA physical layer model consists of data generator, a constellation mapper/demapper, a pair of discrete Fourier transform and channel model. The simulations are performed based on the various of signal to noise ratio (SNR) and number of user in the AWGN and flat Raleigh fading channel models. The bit error rate (BER) performance 10-6 for a single user using QPSK constellation and AWGN channel model is achieved in SNR 4dB. This performance decreases 3dB for multipath channel model.
