噪声消除的DSP算法研究

Research on Noise Elimination of DSP Algorithm Description

随着科技的不断发展,通信系统越来越壮大。背景噪声是通信系统中噪声干扰的主要来源,它使信号变得混杂不清晰,不但降低了语音的品质和可识度,也降低了数字信号的处理能力,如语音识别信道传输和消噪等方面的性能。为了改善噪声环境下声音的质量,降低噪声变得越来越重要。阐述采用DSP技术实现单通道的语音增强系统,利用噪声相减和频谱相减来完成噪音抑制问题。

With the continuous development of science and technology, communication systems grow more and more. Background noise in the communication system is the main source of noise interference, it has become mixed signal and is not clear, quality of the voice and knowledge, and the digital signal processing capabilities are shortened, such as voice recognition channel transmission and denoising. In order to improve the voice of noise environment quality,reduce noise becoming more and more important. Using DSP technology to achieve single voice enhancement system, the use of noise reduction and spectrum subtraction to complete noise suppression.
