Abstract
Disclosed is a method and apparatus which use a first automatic gain control unit to receive a first data signal, use a second automatic gain control unit to receive a reflected radar signal, and switches between using the first automatic gain control unit and using the second automatic gain control unit.
Claims20
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
- transmit a radar signal via a first antenna array, while receiving a reflected radar signal via a second antenna array;
- receive a first data signal or a pilot signal via the second antenna array;
- use a first automatic gain control unit to receive the first data signal, wherein the second antenna array is connected to the first automatic gain control unit, while receiving the first data signal or the pilot signal;
- use a second automatic gain control unit to receive the reflected radar signal, wherein the second antenna array is connected to the second automatic gain control unit, while receiving the reflected radar signal;
- switch between using the first automatic gain control unit and using the second automatic gain control unit.
