ERROR VECTOR MAGNITUDE CONTROL WITHIN A LINEAR TRANSMITTER
摘要
In a portable radio transceiver, such as a mobile wireless telephone, conditions indicative of transmitter distortion (as represented by error vector magnitude (EVM)) are sensed, and transmitted RF power is adjusted in response, so as to reduce distortion and decrease EVM. The conditions can include high VSWR or a combination of high VSWR and low battery power.
