A Novel Bit Error Rate Reduction Method for 3GPP-LTE-SCFDMA Using the Multiwavelet Transform

Abstract: The rapid development of wireless communication technology has brought great convenience to people's lives and work. The goal of next generation of mobile wireless communication system is to achieve ubiquitous, high quality, high-speed mobile multimedia transmission with minimum bit error rate BER. To achieve this goal, the third generation partnership project 3GPP has developed the Long Term Evolution LTE. So, LTE has been considered as one of the core technologies of 4 th generation 4G wireless communication system. The LTE uses the Single Carrier Frequency Division Multiple Access SC-FDMA for uplink because of its ability to reduce BER and peak to average power ratio PAPR as compare to Orthogonal Frequency Division Multiple Access OFDMA that is used in downlink. In this paper a novel approach for implementing the SC-FDMA was proposed using the Multiwavelet Transform MWT instead of Fast Fourier Transform FFT in order to reduce the BER and more robustness against fading channels. The new system was tested under six types of different channels cases. The results show that the proposed system gives lower BER as compare with the old system based on FFT
