1. An electronic device, comprising:
a memory configured to store a tuning state;
an antenna configured to receive a first signal;
a receiver;
a duplexer comprising a tunable component having a plurality of tuning states;
a combiner coupled to the antenna and the duplexer;
a splitter coupled to the duplexer and the receiver; and
a processor coupled to the combiner and the splitter, the processor configured to
combine a second signal with the first signal at the combiner to generate a combined signal,
receive the combined signal at the splitter, and
adjust the tuning state based on the combined signal.
