Sparse Fourier Transform for Performance Enhancement on the Basis of MSE and PC

Malika Singh, S.B.L Sachan

Abstract: The concept of Multiple Input Multiple output (MIMO) with Space Time Block Coding is used for improving the performance of wireless system. Sparse Fourier Transform is developed for estimating the MSE and Pc in system. The design is considered for the AWGN channel. The performance of STBC-MIMO for 8-Quadrature Phase Shift Keying (8-QPSK) is obtained. Furthermore, the proposed algorithm applies with the AWGN channel for estimation. Generally with the increasing value of SNR, the MSE and BER are reduced. Simulations shows good performance in comparison to existing schemes developed for MIMO systems and it is suitable for m- Nakagami fading.
