Power-of-Cosine Window Family


Definition:

$\displaystyle w(n)=w_R(n) \cos^P\left( \frac{ \pi n}{M} \right)$ (4.29)

where $ P$ is a nonnegative integer.


Properties:


Special Cases:

Thus, $ \cos^P$ windows parametrize $ L$ -term Blackman-Harris windows (for $ L=P/2+1$ ) which are configured to use all degrees-of-freedom to maximize roll-off rate.
