<p>The method and apparatus involve receiving (118) one's own transmission with a suitable modulation assessment receiver (119-125) and determining (125) the modulation error relative to the theoretically perfect modulation transmission expected by the receiver. The measured error is used to adjust (110) the modulation to minimize the error. The modulation assessment receiver may use log-polar signal processing (122) to measure phase (124) and (log)amplitude (123) instead of cartesian I and Q components, and then convert (125) to cartesian form.</p> |
