Design of SCFDMA System Using MIMO

Abstract

AbstractThe aim of paper is to design SCFDMA system using SFBC and receiver diversity which provides satisfactory performance over fast fading channel environment. The performance evaluation will be checked through MATLAB R2009b simulator. There are comparisons of performance among 1x1 SCFDMA system, 2x1 SCFDMA system using SFBC, 1x2 SCFDMA system using receiver diversity and 2x2 SCFDMA system using SFBC and receiver diversity. We describe design of SCFDMA system using transmitter diversity technique and receiver diversity technique. We have compared the performance of these systems with the conventional SCFDMA system. The main focus is on design of SCFDMA system using SFBC and receiver diversity which enables desired system to combat detrimental effects of fast fading.Keywords3rd Generation Partnership Project Long Term Evolution(3GPP-LTE)Binary Phase Shift Keying(BPSK)Discrete Fourier Transform(DFT)Inverse Discrete Fourier Transform(IDFT)Localized Frequency Division Multiple Access(LFDMA)Maximum Ratio Receiver Combining(MRRC)Multiple Input Multiple Output(MIMO)Orthogonal Frequency Division Multiple Access (OFDMA)Peak to average power ratio(PAPR)Single Carrier Frequency Division Multiple Access(SCFDMA)Space Frequency Block Code(SFBC)
