This paper concentrates on the development of the Fast Fourier Transform (FFT), based on Decimation-In-Time (DIT) domain, Radix-2 FFT algorithm and Split Radix FFT Algorithm and finally architectures by two different algorithms are compared for speed and device utilization. This paper concerns ...
the split-radix 2/4 FFT algorithm是什么意思?相关知识点: 试题来源: 解析 FFT 即 Fast Fourier Transform:快速傅里叶变换split-radix 即“分裂基算法”,同时使用基2和基4算法,被认为是目前对于N=2L 各类算法中最为理想的一种algorithm 即 “算法”不过具体的我也没自己研究过,稍微听过而已...

(SRFFT) pipeline architecture design. A mapping methodology has been developed to obtain regular and modular pipeline for split-radix algorithm. The pipeline is repartitioned to balance the latency between complex multiplication and butterfly operation by using carry-save addition. The number of ...
The new proposed algorithm for computing a length L=2Bx3C FFT. It is used to minimize the twist of hardware depict and arithmetic operations. Additionally, the propound fragment design can accomplish by the mixer of radix-3 and radix-2Bx3C FFT algorithm. It is entirely changeable of Split ...
An extension of an existing fast algorithm for the computation of the discrete cosine transform is presented. The proposed algorithm has a structure similar to the split-radix algorithm used for the computation of the FFT, the same computational complexity as the direct fast cosine algorithms and ...
split-radix algorithm is the best in terms of the multiplicative complexity for -point FFT when the multiplications with 1, are skipped. However, split-radix algorithm is inherently irregular because radix-2 stages are used for even half com- ...
