(BlueNRG) How to obtain the carrier signal function on the Rx without decoding

[JasonYang]

Currently, I have two STEVAL-IDB011V2 boards (as shown in the figure). One is to send the signal as a transmitter, and the other one is the receiver. After the channel (between Tx and Rx) modulates the signal, how can I extract the carrier signal without decoding on the Rx? Does anyone know the function of this? Thanks!
