Simulation and performance evaluation of multi-channel DTMF receivers signal detection algorithm using LP

LP를 이용한 다중채널 DTMF 수신기 신호검출 알고리즘의 시뮬레이션 및 성능평가

The economical detection of dulal-tone multifrequency(DTMF) signals is an important factor when developing cost-effective telecommunication equipment. Each channel have independently a DTMF receiver, and it informs the detected signal to processors of the TDX. This paper proposes the linear prediction algorithm for the spectrum analysis. As a experimental resutls, it can obtain the improved performance to the DTMF receivers and reduce the real-time processing and memory waste.
