Claim Text:
1. A method for controlling output signal power in a communication terminal, the method comprising: accepting, from first and second measurement points along a transmission chain in a transmitter of the terminal, respective first and second signal representations of a communication signal to be transmitted by the communication terminal; selecting whether to route the first and second signal representations to a first processing path that detects respective first and second envelopes of the first and second signal representations, or to a second processing path that does not apply envelope detection to the first and second signal representations; time-aligning the first and second signal representations, or the first and second envelopes, depending on the selected processing path; computing an actual gain between the first and second measurement points using the time-aligned first and second signal representations or first and second envelopes; and adjusting an output power of the communication signal by setting a gain of the transmitter responsively to the actual gain.
