System for Tuning an Antenna Using Injection

Abstract

A method for wireless communication includes adding a received DVB-H signal with a reference oscillator signal to generate an added DVB-H signal. The reference oscillator signal may be added at an input of a matching load. The matching load may be used to tune a wireless antenna that receives the received DVB-H signal based on a received signal strength indicator (RSSI) associated with the added DVB-H signal. The reference oscillator signal may be generated, and the generated reference oscillator signal may be amplified. The added DVB-H signal may be amplified subsequent to the adding. The RSSI associated with the added DVB-H signal may be determined. The tuning may occur during receiving of a preamble of a packet for the received DVB-H signal.
