Multirate Hardware of Architecture for Real-Time Fourier Transform Analysis/Synthesis
Mohammed Bahoura · 2020
This paper presents a simple and efficient multirate hardware architecture for real-time signal processing applications. The proposed architecture is based on two special buffers: the input buffer transforms a given input signal to an upsampled and time-scale compressed form that highly reduces the calculation time of its Fourier transform analysis/synthesis to achieve real-time performance. The output buffer transforms back this frame to its original time-scale and sampling frequency. This architecture has been implemented and tested on FPGA (field programmable gate array) chip using XSG (Xilinx system generator) tool in MATLAB/SIMULINK environment.
