Expander implementation using filter banks

The MWC system has a few physical channels, each of them contain a certain amount of hardware units. Reducing the amount of the physical channels is the key to prevent burden on the hardware. A way to trade the amount of physical channel’s with a higher sampling rate was developed. It combine every few physical channels into one. The Expander is used for separating back the channels. The goal of this project is to implement the Expander using filter banks.
