Current analyses of the watermarking channel are typically limited to the additive white gaussian noise ( awgn ) channel 当前典型的水印信道分析被限制在加性白高斯信道上。
In the presence of additive white gaussian noise , an adaptive wavelet - based de - noising algorithm for speech enhancement applications is proposed 针对加性高斯白噪声的情况,提出一种自适应小波降噪算法,用于语音信号的增强。
In awgn ( additive white gaussian noise ) channel , we introduce a new single - tone interference suppression scheme in the single - tone interference environment 针对加性白高斯噪声信道中的发射信号,提出了利用单音信号频域特性的单音干扰抑制方法。
Subsequently the channel was modeled for three types namely additive white gaussian noise , flat fading and frequency selective fading . lastly , the receiver was studied 接下来信道建模成三种不同的类型,即加性高斯白噪声信道、平坦衰落信道和频率选择性衰落信道。
Sinusoidal frequency estimation is the procedure which can estimate the frequency of sinusoidal waves in additive white gaussian noise through transform and calculation for signal ' s samples 正弦信号频率估计是指通过对信号采样值的计算和变换,估计出淹没于噪声中的信号的频率的过程。
Additive white Gaussian noise (AWGN) is a channel model in which the only impairment to communication is a linear addition of wideband or white noise with a constant spectral density (expressed as watts per hertz of bandwidth) and a Gaussian distribution of amplitude. The model does not account for fading, frequency selectivity, interference, nonlinearity or dispersion.
