Abstract

In order to improve the security of using mobile phones and prevent the theft of mobile banking passwords, this paper makes a deep research on the recognition technology of listening dial tone based on Goertzel algorithm of Matlab platform system simulation. Goertzel algorithm is the most classical and practical method to estimate the power spectrum of Dual Tone multi-frequency (DTMF) signal. DTMF dialing system has the advantages of convenient frequency domain analysis and strong anti-interference ability. The algorithm only estimates the power spectrum at two specific frequency points of DTMF signal, and it can deduce the key value from the corresponding relationship of frequency array on the keyboard.
