Description

The IDCT block computes the inverse discrete cosine transform (IDCT) of the input frame. For a length-M input U, the IDCT is given by:

where

Multichannel inputs (i.e., frame matrices) are not accepted. The output of the block is a frame with the same size, period, and data type (real/complex) as the input.
