multiple users and data streams must be processed concurrently in a contemporary communication system based on existing 4G and future 5G technology. Channelization, which is used to segregate many users or channels from a single communication stream, requires a front-end transceiver to be able to broadcast and receive several channels at the same time.
A channelization process is in charge of three fundamental tasks:
1. Signal up/down conversion (mixing)
2. Sample rate change
3. Filtering
