摘要

PURPOSE: A microphone noise removal method and a portable terminal supporting this are provided to remove noise included in a microphone signal of a portable terminal and to provide better service quality. CONSTITUTION: A microphone noise removal method and a portable terminal supporting this collect a microphone signal through a microphone signal line and collect a noise signal discarded in a noise collection circuit arranged in the adjacent region. The portable terminal generates a compensation signal using the noise signal for removing noise included in the microphone signal using the noise signal(109) and removes the noise included in the microphone signal through the compensation signal(111).
