✦ Synopsis

A multi-radix ,fust Fourier transform/number theoretic transftirm is proposed ,ftir the calculation of the discrete Fourier transform of sequences with a prime length, P. The proposed technique is applicable to sequences of length P = 2"' * 3K2* SK3+ 1, where Kl, K2 and K3 are integers. Advantages include availability of fast algorithms for a set of prime lengths, residue arithmetic with benefit in speed and hardware cost andparallel implementation. A Discrete Power Spectrum example is included.

Many fast algorithms have been proposed for computing the discrete Fourier transformation. Most of them are based on factorization with the goal of reducing the number of multiplications. They usejoating point arithmetic to avoid repetitious scaling and a sizeable wordlength to minimize quantization
