Electronic device and signal processing method thereof

The invention discloses an electronic device and a signal processing method thereof. The method includes that a first signal pathway module in the electronic device receives radiofrequency signals through a main set of antennas and transmits the received radiofrequency signals to at least one radio frequency module for processing, or transmits at least one radiofrequency signals sent by the at least one radio frequency module and sends the radiofrequency signals through the main set of antennas; a second signal pathway module receives radiofrequency signals through a diversity antenna used by the second signal pathway module and sends the radiofrequency signals to at least one radio frequency module for processing; a GPS signal pathway module receives GPS signals through a GPS antenna used by the GPS signal pathway module and sends the GPS signals to at least one radio frequency module for processing; and at least one radio frequency module receives GPS signals through the GPS signal pathway module and at least one signal pathway module in the second signal pathway module. The influence of multipath effect of GPS signals on reception performance of the GPS signals on reception performance of GPS signals during reception of GPS signals.
