Realization and Code Optimization of Fast Fourier Transform Based on DSP
快速傅里叶变换的DSP实现及代码优化

The algorithm theory and features of the DIT radix-2 Fast Fourier Transform is introduced.And the author then study the Fast Fourier Transform process and program optimization with Digital Signal Processor in detail.Finally,the thesis uses MATLAB to do many simulations and research on this algorithm.Simulation results shown that this method has many special features such as high precision and fast.
