Example: Polyphase Analysis of the Weighted Overlap Add Case: 50% Overlap, Zero-Padding, and a Non-Rectangular Window
We may convert the previous example to a weighted overlap-add
(WOLA) (§8.6) filter bank by replacing each
by
and introducing these gains also between the
and
upsamplers, as shown in Fig.11.27.
