ABSTRACT:
Certain aspects of a method and system for simultaneous FM transmission and FM reception using a shared antenna and a direct digital frequency synthesizer (DDFS) may be disclosed. In a FM transceiver that receives FM signals at a frequency f1and transmits FM signals at a frequency f2, aspects of the method may include generating via a DDFS, a signal corresponding to a difference between f1and f2to enable simultaneous transmission and reception of FM signals via shared antenna.
