Performance Comparison of FFT and DWT based MIMO-OFDM Communication Systems
In this paper, the performance of Dicrete Wavelet Transform (DWT) based Multi-user MIMO-OFDM is compared with the performance of FFT based MIMO-OFDM system. Wavelet based OFDM has lot of advantages compared to the FFT based OFDM. There is no need for cyclic prefix, flexibility and optimal resolution. Wavelets existed suitably in almost all the arenas of wireless communication schemes with OFDM ...
متن کاملPerformance Analysis of Ber Using Dwt Based Mimo-ofdm System
Orthogonal frequency division multiplexing (OFDM) has been considered as a promising technique for future wireless communication system for high data rate and mobility. OFDM is used as both modulator and multiplexer. In recent years, Multiple – Input Multiple – Output (MIMO) wireless communication systems have received a lot of attention. MIMO boost up the channel capacity and speed. Though OFD...
متن کاملPerformance Comparison of Wavelet and FFT Based Multiuser MIMO OFDM over Wireless Rayleigh Fading Channel
This article examines the performance of Wavelet based Multi-User MIMO OFDM (MUMIMO WOFDM) systems and a comparison is made with classical FFT based multiuser MIMO OFDM system. Wavelet analysis has some strong advantages over fourier analysis, as it allows a time-frequency domain operation, allowing optimal resolution and flexibility. Wavelets have been satisfactorily applied in almost all the ...
متن کاملPerformance Analysis Comparison of FFT and Discrete Wavelet Packet Transform (DWPT) Based MIMO-OFDM Systems
Multiple Input Multiple output (MIMO) antennas can be combined with orthogonal frequency division multiplexing (OFDM) to ensure spatial diversity gain and/or to increase spectral efficiency. MIMO communication system with Alamouti methods can improve the bit error rate (BER) and signal to noise ratio (SNR) thus distortions are reduced for higher data rate. Conventionally OFDM is Fast Fourier Tr...
متن کاملArea-efficient FFT processor for MIMO-OFDM based SDR systems
In this letter, an area-efficient FFT processor is proposed for MIMO-OFDM based SDR systems. The proposed FFT processor can support variable lengths of 64, 128, 256, 512, 1024, 1536 and 2048. By reducing the required number of non-trivial multipliers with a mixed-radix algorithm, the complexity of the proposed FFT processor is dramatically decreased. The proposed FFT processor was designed in a...
