Embodiment Construction

[0022] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] High-frequency noise processing method of the present invention, as shown in Figure 2, comprises:

[0024] Step S202, the receiving end performs short-term energy analysis on the received speech data and compares the short-term energy of the obtained speech data with the energy threshold, if the short-term energy of the speech data is greater than the energy threshold, the speech data is a voiced signal, otherwise for unvoiced signals.

[0025] Step S204, perform pitch frequency analysis on the voiced sound signal and compare the pitch frequency of the obtained voiced sound signal with the pitch frequency threshold, if the pitch frequency of the voiced sound signal is greater than the pitch frequency threshold, the voiced sound signal is a high-frequency noise signal, otherwise it is a normal voiced sound Signal.

Abstract

The invention provides a high-frequency cracks processing method which comprises that: the first step: a receiving terminal has a short-time energy analysis on received speech data; the short-time energy of the achieved speech data is compared with an energy threshold value; if the short-time energy of the speech data is greater than the energy threshold value, the speech data is a sonant signal, otherwise, the speech data is a surd signal; the second step: the sonant signal is processed by basetone frequency analysis and the basetone frequency of the received sonant signal is compared with a basetone frequency threshold value; if the basetone frequency of the sonant signal is greater than the basetone frequency threshold value, the sonant signal is a high-frequency cracks signal, otherwise, the sonant signal is a normal sonant signal; the third step: the judged high-frequency cracks signal is analyzed and processed. The invention also provides a high-frequency cracks analytical method. Through the high-frequency cracks processing method and the analytical method provided by the invention, the high-frequency cracks in the normal speech signal can be judged and data source is recorded, further the cause for producing the high-frequency cracks is analyzed, thereby solving the produced problems.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for judging voice noise. Background technique [0002] The main components of the existing mobile network are: Mobile Terminal (MS), Base Station (BTS), Base Station Controller (BSC), Mobile Switching Center (MSC) and other transmission equipment. Specifically related to voice business processing mainly for BTS and BSC. The BTS mainly includes a radio frequency system and a channel unit. The radio frequency system completes the conversion of radio frequency and baseband signals, and the channel unit completes the modulation and demodulation function of the baseband signal. The BSC mainly completes the service adaptation function, including the processing of unlimited call signaling, the management and allocation of resources, and the adaptation processing of voice and data services.
