Estimating parameters of hyperbolic modulation frequency signal based on cascade dictionary

为降低水下通信中出现的多径和多普勒效应,提高水下目标探测精度,采用双曲调频信号作为探测信号,利用双曲调频信号(hyperbolic modulation frequency,HFM)时频变化具有双曲线的特征,通过建立HFM信号时间-尺度级联原子库模型,在原子库中寻找最优解,进而对HFM信号的两个频率变化因子进行估计。计算机仿真和水池实验的结果均证明,相较于现在常用的小波-拉东变换(wavelet-Radon)估计方法,本方法的均方根误差小于1%,因此在水下目标探测中有较大的应用价值。To reduce the multi-path and Doppler effects occurring in underwater communications and to increase the precision of underwater target detection,we employ a modulation frequency signal as the detection signal. A hyperbolic modulation frequency( HFM) signal is hyperbolic in the time-frequency domain. In view of this feature,we establish a time-scale cascade dictionary model to find the optimal solution; furthermore,two frequency variation factors of the HFM signal are estimated. The simulation results and the pool trials show that the proposed algorithm performs well,and its accuracy is superior to that of the commonly used wavelet-Radon transform. The root mean square error of the frequency variation factors is 1% lower than that achieved using the wavelet Radon transform.This demonstrates the potential of the suggested algorithm for underwater target detection.国家自然科学基金项目(61471309,61107023);; 国家教育部博士点基金项目(20110121120020);; 福建省自然科学基金项目(2013J01258);福建省自然科学基金项目(2010J01344);; 福建省重点基金项目(2012H1012

复杂性后尿道狭窄81例治疗分析

目的探讨复杂性后尿道狭窄或闭锁的手术治疗方法,提高手术治疗效果。方法 1991～2008年收治的81例复杂性后尿道狭窄/闭锁患者,狭窄/闭锁段长度为3～10cm,其中>5cm者27例;66例曾有1～4次手术史;62例行改良尿道套入术,19例尿道端端吻合术;73例经会阴或腹会阴切口,8例经耻骨或切除部分耻骨下缘切口。15例应用尿道替代物成形。结果 76例(93.8%)术后排尿满意,5例失败,其中改良尿道套入术和尿道端端吻合术成功率分别为95.2%(59/62)、89.5%(17/19)(P>0.05)。15例应用尿道替代物成形术均取得成功。结论复杂性后尿道狭窄/闭锁的治疗应根据尿道病变情况选择不同的手术径路及术式,改良尿道套入术具有创伤小、操作简便、成功率高等优点。尿道狭窄段>5cm者应考虑应用尿道替代物成形

The Methods of Abstracting Chinese Dot Matrix for Embedded Systems

嵌入式系统人机交互性能的重要指标之一是汉字显示打印功能,利用汉字点阵实现此功能是一种简单实用的方法,因此从现有汉字系统中提取汉字点阵是嵌入式系统开发的第一步工作。提取汉字点阵有两种方法,一是从点阵字库中提取,二是从矢量字库中提取,这两种方法在实际开发工作中都得到了应用。详细分析了这两种方法的原理及编程实现,提出了自动扫描嵌入式应用程序生成汉字点阵的方法,这种方法特别适用于建立小型汉字点阵库。It′s a simple and practical method to use the Chinese dot matrix to display and print Chinese characters in embedded systems.Therefore,abstracting dot matrixes from the existing Chinese character OS is the first step of developing embedded system.We can abstract dot matrixes from the dot matrix library or from the vector library.Authors have applied both ways in practical applications.This paper analyses the principles and programming of both ways in detail.In addition,this paper proposes a method of auto-scanning source files,this method is best for creating mini dot matrix library.厦门大学985二期信息创新平台项目资
