Description: 分析了相位噪声对正交频分复用(OFDM)系统的影响,发现相位噪声不仅产生
通用相角错误(CPE),而且还会产生载波间干扰(ICI),这都使OFDM系统的性能急剧恶
化,因此必须对CPE和ICI进行校正.文中给出了基于MSE准则的CPE校正方法,考虑到
ICI干扰主要来源于相邻信道,进而提出了基于LMS法则的自适应相邻信道干扰消除方
法.整个算法简单高效.仿真结果表明,所提出的算法大大改善了OFDM系统的性能-Analysis of phase noise on the orthogonal frequency division multiplexing (OFDM) system, the impact of phase noise was found not only from the general phase angle error (CPE), but also generate inter-carrier interference (ICI), which are so dramatically the performance of OFDM system worse, it is necessary CPE and ICI correction. This paper gives guidelines for CPE-based MSE correction methods, taking into account ICI mainly come from the adjacent channel interference, then presents a rule-based LMS adaptive adjacent channel interference cancellation method. the algorithm is simple and efficient. The simulation results show that the proposed algorithm greatly improved the performance of OFDM systems

Description: Abstract—In this paper, we consider distributed estimation of
a noise-corrupted deterministic parameter in energy-constrained
wireless sensor networks from energy-distortion perspective.
Given a total energy budget allowable to be used by all sensors,
there exists a tradeoff between the subset of active sensors and
the energy used by each active sensor in order to minimize the
estimation MSE. To determine the optimal quantization bit rate
and transmission energy of each sensor, a concept of equivalent
unit-energy MSE function is introduced. Based on this
concept, an optimal energy-constrained distributed estimation
algorithm for homogeneous sensor networks and a quasi-optimal
energy-constrained distributed estimation algorithm for heterogeneous
sensor networks are proposed. Moreover, the theoretical
energy-distortion performance bound for distributed estimation
is addressed and it is shown that the proposed algorithm is
quasi-optimal within a factor 2 of the theoretical lower bound.

Description: 在分析最小均方自适应滤波器(LMSAF)均方误差(MSE)的收敛性时，文献常用统计自相关矩阵代替瞬时自相关矩阵以简化分析，由此得出的收敛条件比较粗糙。本程序指出：不相关高斯输入情况下，无需如上简化，可依据高斯阶矩因式分解定理得到确切的MSE收敛条件，相应的失调表式能更准确地预报失调-In the analysis of LMS adaptive filter (LMSAF) the mean square error (MSE) convergence, the literature commonly used statistical correlation matrix instead of the instantaneous correlation matrix to simplify the analysis, it follows that the convergence conditions are relatively rough. This procedure pointed out: not related to the Gaussian input case, no simplification above may be based on the Gaussian moment factoring theorem to the exact order of MSE convergence conditions, the corresponding offset table style to a more accurate prediction of disorder

Description: The LMSE package contains two subroutines. LMSE computes the minimum mean square error (MSE) possible if one image is allowed to be linearly scaled in intensity. LMSEDIFF computes the difference image after the target image is scaled according to the scaling that minimizes the MSE. This is a better way to compare images if the absolute magnitude of the intensity has no meaning.

Description: main executing reference usage: observeWaveletDecompositionBenchmark_N_levels.m
The objective is to illustrate wavelet decomposition, and to describe how operations may be done in the wavelet domain before the reconstruction. The demo decouples the wavelet operations (transform, operation in wavelet domain, and reconstruction) from the plotting.
A PSNR and MSE describes the possible distortion (however minimal) of the forward and inverse wavelet transform.
* Caveat: The image display may be subjected to the selected target image. The objective is to provide a simple framework for the understanding of working with wavelets.

Description: 图像质量评价方法研究进展
：图像质量评价是图像处理领域的研究热点。该文综合论述了图像质量的主观和客观评价方法，重点阐述了
单视点图像质量的客观评价方法。对目前比较常用的峰值信噪比和均方误差全参考评价算法进行了分析并指出其存
在的问题。然后，对基于误差敏感度和基于结构相似度的评价算法进行了论述和分析，并对质降和无参考评价方法
进行了综述。根据视点的个数，图像质量评价可分为对传统单视点图像和立体图像的评价。该文还对立体图像质量
评价算法进行了分析讨论。最后，就图像质量评价算法的进一步发展提出了若干技术与研究方向的展望。-Image Quality Assessment (IQA) is a hot research area in the field of image processing. In this paper,
objective and subjective IQA methods are reviewed, and more attention is paid to the former. PSNR and MSE,
which are commonly used to assess the quality, are analyzed in detail and their defects are given. The models based
on error sensitivity and structure distortion of images are two critical methods in IQA, and the survey presents
their key techniques and challenge problems. The reduced reference and no reference methods are also presented in
this survey. Based on the number of view, IQA are classified into two major categories, namely, monoscopic image
IQA and stereoscopic image IQA. This survey also makes an introduction of the stereoscopic image IQA. Finally,
the survey lists several perspective sub-fields and topics in IQA progress.
