ADJACENT CHANNEL REJECTION
In FSK mode, the unwanted signal is unmodulated (as described in the EN 300-220). Co-channel rejection (CCR, offset = 0 kHz) is
positive due to the DC cancellation process of the zero-IF architecture. In OOK mode, the polyphase filter efficiency is limited, thus
limiting the adjacent channel rejection at 2xFo distance.
