A spatial 3-D nonlinear correction technique is put forward to correct the nonlinearity errors of the PSD in long distance laser collimating measurement. An automatic calibration system is developed to measure the nonlinearity of a 2-D PSD in 3-D space. The nonlinear characteristic of 2-D PSD is checked in a long collimating distance of 78 meters. The experimental results show that the nonlinearity of 2-D PSD is different evidently when the PSD element is at different position from the laser head. The spatial 3-D mapping relationship between the actual displacements of the incident light and the coordinates of 2-D PSD outputs is established by using a multilayer feed forward neural network and the nonlinear errors are corrected with this map. The readout errors of the PSD after correction are shown as random and no more than±0.012 mm in the whole measuring distance.

Association rule discovery, as the kernel task of data mining, has been studied widely. However, most algorithms based on frequent item sets have to scan databases many times. This reduces the algorithms' efficiency. Formal concept analysis is a useful tool in many fields. In this paper, an association rule mining algorithm is proposed based on the formal concept analysis. Through analysis the relationship between concepts in different levels, we can simplify the process of discovery association rules. Experiments on real dataset demonstrate the effectiveness of our methods.

The previous image quality assessment(IQA) methods request the same size of original and distorted image, not suitable for the super-resolution image. The effective of image size change has rarely been discussed. An improved reduced-reference image quality assessment (RRIQA) method based on the structural similarity image metric(SSIM) and scale invariant feature transform(SIFT) was put forward. The method is applicable to the super-resolution image, and considering more than one reference image. Experimental comparisons demonstrate the effectiveness of the proposed method.

For the Satellite Navigation Receiver of CDMA system, the circuit which is passive should have well characteristics on amplitude and phase within the pass band, especially in anti-jamming receiver. But the filters in the last cascade of reviver's analog circuits are primary causes of non-ideal channel characteristics so that group delay equalization is efficient and necessary. Narrowband group delay equalization, which can't satisfy wideband filter, has been improved to a wideband group delay equalization of satellite navigation receiver. The thesis analyzes and designs a high-order equalization based on Centro Symmetric Equalization Method. By simulating and producing actual circuit, the performance of third-order and fifth-order group delay equalization networks are compared and analyzed. Finally, the fifth-order wideband group delay equalization circuit is cascaded with the filter of navigation receiver that the maximum group delay of pass band has been reduced to 5 ns between full bandwidth, 10% of before. This method has been applied on a wideband high measurement accuracy anti-jamming navigation receiver and improved the group delay characteristics from the analog frond-end.
