ABSTRACT:
Certain aspects of a method and system for tuning an antenna using injection may include mixing a received DVB-H signal with a reference oscillator signal to generate an added DVB-H signal. A mixed signal may be generated from the added DVB-H signal using the reference oscillator signal. A wireless antenna that receives the received DVB-H signal may be tuned based on a received signal strength indicator (RSSI) associated with the mixed signal. The reference oscillator signal may be generated and then may be amplified. The first mixed DVB-H signal may be amplified prior to the generating of the mixed signal. The RSSI associated with the mixed signal may be determined. The tuning may occur during receiving of a preamble of a packet for the received DVB-H signal and/or during receiving of a plurality of packets for the received DVB-H signal.
