信号空间 meaning in Chinese
signal space
Examples
- Study on the application of fractal theory to the analysis of the space - series of seismic prospecting signal
基于分形理论的地震信号空间序列分析 - The tcq algorithm takes advantage of convolution code , and enlarges the euclidean distances among quantized data by expanding data dimensions
Tcq算法充分利用了卷积码的特性，采用信号空间扩展的方法来增大量化信号的欧式距离，从而达到提高量化性能的目的。 - In the wireless systems , smart antenna techniques use the signal ' s spatial signature to improve system performance . but up to now there is still no commercial smart antenna system in large use
在无线通信中，智能天线可以充分利用信号空间特性提高系统性能，但现在还没有大规模商用的智能天线系统。 - In signal space , speech enhancement is adopted to effectively suppress the noise and increase the discriminative information embedded in noisy speech signal . however , the speech distortion introduced by enhancement , as well as the residual noise , is a very adverse factor for recognition
在信号空间，利用语音增强有效抑制噪声，提高输入信号中的鉴别信息，但增强带来的语音失真和增强后的剩余噪声是对语音识别非常不利的因素。 - In the thesis , an approach that is based on signal - space concepts is used to efficiently evaluate the ber performance of mpsk and mqam over an additive white gaussian noise channel . in particular , accurate ber approximations are obtained and shown to be in good agreement with system simulation results . it may be useful to research and development of digital modulation technologies in hfc of our country
尝试采用基于信号空间的分析方法，给出了awgn信道中mpsk和mqam的ber的计算方法以及由这种方法得到的ber性能曲线，然后将信号空间分析法得到的结果与通信系统仿真的结果进行比较，证明其与仿真结果较好地吻合。
