Prime factor decomposition 分解质因(Prime factor decomposition)是指每个合数都可以写成几个质数相乘的形式,其中每个质数都是这个合数的因数,把一个合数用质因数相乘的形式表示出来。 如30=2×3×5 。分解质因数只针对合数。 1定义 编辑 把一个合数分解成若干个质因数的乘积的形式,即求质因数的过程叫做分解质因数...
Skew-circular/circular correlation decomposition of prime-factor DCT An algorithm to decompose the prime-factor DCT into skew-circular/circular correlation (SCC/CC) by coset decomposition is proposed. The simplest case is when the two factors are odd and relatively prime. In this case, the DCT ...
A direct-sequence spread spectrum (DSSS) receiver may be operable to process signal samples in frequency domain utilizing a prime factor fast Fourier transform (FFT) circuit and a pseudorandom noise (PRN) code. The DSSS receiver may be operable to transform the signal samples into FFT signal ...
The prime-factor DCT algorithm of two relatively prime factors decomposing the DCT matrix into skew-circular correlation (SCC) matrices and circular correlation (CC) matrices is generalized to many factors. As a result, the DCT output components are divided into several parts, each part is a ...
