Negacyclic convolution
Encyclopedia
In mathematics, negacyclic convolution is a convolution between two vectors a and b.
It is also called skew circular convolution
or wrapped convolution. It results from multiplication of a skew circulant matrix, generated by vector a, with vector b.
It is also called skew circular convolution
Circular convolution
The circular convolution, also known as cyclic convolution, of two aperiodic functions occurs when one of them is convolved in the normal way with a periodic summation of the other function. That situation arises in the context of the Circular convolution theorem...
or wrapped convolution. It results from multiplication of a skew circulant matrix, generated by vector a, with vector b.
