Sub-band synthesis filter

Can anyone point out about sub-band synthesis filter used in DAB systems MPEF audio layer II decoder?
I have the algorithm for sub-band analysis filter that is used in MPEG layer
II encoder. But i am unable to understand how the reverse process is acheived with the same parameters as that in encoder.

If someone can provide me the algorithm in terms of mathematical equations, it will be great.
