邻道干扰(ACI)抑制中需要获取干扰信号非线性特征进行信号重建与抵消,因此接收机需使用高速率宽带模数转换器(ADC)采集干扰信号,这将大幅增加接收机成本。 |
In Adjacent Channel Interference (ACI) suppression, in order to obtain the nonlinear characteristicsof interference signal for reconstruction and cancellation, the receiver needs to use high-sampling-rate widebandAnalog-to-Digital Converter (ADC) to sample interference signal, which will greatly increase the cost of thereceiver. |

利用接收的干扰信号带外非线性分量,计算并消除相邻帧之间的影响,由窄带部分卷积信号帧构造出线性卷积信号帧,然后用正则化最小二乘方法恢复原始非线性宽带干扰信号,从而降低ADC采样率。 |
By using the known out-of-band nonlinear component, theinfluence between adjacent frames is calculated and eliminated, and then the narrow band linear convolutionframe is constructed from the partial convolution frame. Finally, the original wide band signal is recovered byregularized least square method, thus reducing the ADC sampling rate. |

首先将图像进行亮度系数归一化处理,然后将图像进行分块,利用卷积神经网络(CNN)进行端对端的深度学习,采用多层次卷积核堆叠的方法获取图像的质量感知特征,并通过全连接层将特征映射到图像块的质量分数。 |
Firstly, the brightness coefficients of the image are normalized, and the image is divided into blocks. While the Convolutional Neural Network (CNN) is used for end-to-end depth learning, the multi-level stacking of convolution cores is applied to acquire image quality perception features. The feature is mapped to the massfraction of the image block through the full connection layer, then the quality pool is obtained by aggregatingthe quality of the block. |

再将块质量分数汇总获取质量池,通过对质量池中局部质量的空间分布情况进行分析,提取能够表征其空间分布情况的特征,然后采用神经网络建立局部质量到整体质量的映射模型,将图像的局部质量进行汇总。 |
Through the analysis of the spatial distribution of local quality in the quality pool, thefeatures that can represent its spatial distribution are extracted, and then the mapping model from local qualityto overall quality is established by the neural network to aggregate the local quality of the image. |
