1. A receiver comprising:
a received signal strength indicator (RSSI) circuit configured to receive a signal from an antenna;
an edge detection circuit coupled to the RSSI circuit and configured to detect a new incoming signal compared to an existing environment;
a synchronization circuit configured to use a correlation algorithm to synchronize to the signal from the antenna; and
a control circuit coupled to the edge detection circuit and the synchronization circuit and configured to:
turn off the synchronization circuit; and
responsive to detection of the new incoming signal by the edge detection circuit, turn on the synchronization circuit.
