Performance Analysis of Space Time Block Coding for Wireless System using SFT

S. B. L Sachan, Malika Singh

Abstract: Wireless systems generally deals with the concept of system reliability and spectrum efficiency along with network coverage.For improving the performance of wireless system the concept of Multiple Input Multiple output (MIMO) with Space Time Block Coding is used. Sparse Fourier Trasform is developed for estimating the orders response and Bit error rate in system.The design is considerd for the total noise reduction. The error reduction of STBC-MIMO for 8-Quadrature Phase Shift Keying (QPSK) is obtained. Furthermore, the proposed algorithm applies with the different channels for system order es-timation. Simulations in the context of different channels order estimation shows good performance in comparison to existing schemes developed for MIMO systems.
