The main job and contribution of this paper are as follows:Based on narrowband signal processing, we propose a new method for FH signal blind detection and blind parameter estimation. Firstly, compute the cross-correlation function of FH signals from multichannels, then we get the cross power spectral density matrixCSDM Secondly, select the hops of FH signals from the CSDM via processing and analyzing the CSDM, meanwhile reduce the influence coming from noise, fixed frequency signal and other interferences; Lastly, estimating the DOA of every hop and according to the DOA, we can separate the hops, get the number of FH signals and their parameters. Propose a new method for designing the threshold in FH signal detection. This method makes it easy to get the threshold by theoretic computing and it can extremely reduce the interference of non-FH signals.Based on broadband signal processing, we propose a new method for FH signal blind detection and blind parameter estimation. Firstly, get the DOA of the signals by wideband spatial spectrum estimation; secondly, separate the signals by spatial filtering using wideband beamformer; Lastly, we propose two methods for FH signal blind detection and blind parameter estimation, one is for several constant hop-rate FH signals whose dwell-time are different and another is for a single FH signal whose hop-rate is alterable.By employing spatial interpolation in broadband signal beamforming, it can reduce the number of antenna elements and corresponding RF modules, A/D converters, etc. It can also eliminate the mutual coupling between antenna elements while getting the narrower main beamwidth and lower sidelobe level.

本文的主要研究工作和贡献如下：●提出了一种基于窄带处理的FH信号盲检测和参数盲估计的实现方法，即首先求出多路信号之间的互相关，进而得到互功率谱密度矩阵，然后通过对CSDM进行对折处理来抑制噪声、定频信号及其他干扰的影响，并将所有属于FH信号的hop(每一跳的驻留时间在时频图上持续的线段)从CSDM中筛选出来，最后用阵列信号处理中的到达方向估计理论在频域中估计出各个hop的方向参数，利用方位信息完成FH信号分离并得到FH信号的数目及其各自的参数集；●提出了一种确定FH信号检测门限的策略，该策略不仅使得检测门限能够通过理论计算得到，而且还显著地抑制了非跳频信号的干扰，从而能有效地检测出FH信号；●提出了一种基于宽带处理的短波FH信号盲检测和参数盲估计的实现方法，即首先利用宽带空间谱测向技术得到接收信号的DOA，然后采用宽带波束形成技术对特定方向进行空间滤波，实现多个信号的分离，最后分别提出了两种FH信号的盲检测和参数盲估计方法，第一种方法适用于空间某个特定方向上存在着几个驻留时间不同的恒跳速FH信号和其他干扰信号的混合信号，第二种方法适用于空间某个特定方向上仅含一个可变跳速的FH信号和噪声的混合信号；●将空间插值的概念和宽带波束形成技术结合起来，提出了一种基于频域处理的宽带恒定束宽的波束形成方法。

According to the localization principle of the DV-Hop algorithm, this paper proposes three improvements including the estimation of average single hop distance, the calculation of distance between unknown nodes and reference nodes and the estimation of node positions. These improvements can be used independently or jointly to replace the corresponding steps in the DV-Hop algorithm. The localization performances are analyzed in theory and with simulations.

A total of 45 hip joints with Perthes'disease were examined with ultrasound imaging including CDFI in order to observe the characteristics of hip joints blood supply, while the normal hip joints in the same 45 cases were examined as the controls.

There are some details worth to mention. Any who watched some of Law's roles could feel his profession at "style". But on Hip Tin, his application of style reached such a high degree that exaggeration could be sensed, from which the minus effect created just satisfied the requirement of "abnormal". For example, when Hip Tin wrote time periods for stocks himself before asking Bok to write the prices from memory , a stylish move was seen: Turn around, writing vigorously by one hand with another hand quickly moving at his waist. Such a small move not only matched Hip Tin's confidence and pizazz as "God of the Wall Street",but also implied his madness by its exaggeration which had the big difference between a normal move.

这里有几个细节值得一提：但凡看过一些罗大侠作品的人都可体会到他对于"型"的擅长，而在叶天身上，他注入的"型"明显高到了夸张的地步，如此一来触发的反效果恰与"非正常"三字一拍即合，譬如他在要求展博默出股票全日造价并在黑板上写下该股各时段时一个很"型"的小动作：转身和叉腰，即符合叶天"神"的潇洒和自信，又因动作极其夸张而与正常人的反应相去甚远，继而成为其病征的隐含交代--这样充满分裂感的动作还有很多：盘膝坐在桌上居高临下对展博训话，叶天世界里的目空一切--现实中病态的表现；满怀激情送走得意门生后在废墟中享受的回眸，但之前又伴随了一个虚弱的踉跄脚步--心力和体力分裂的表现。

The study's primary end point was the incidence of hip fracture. At the end of the trial, hip fractures had occurred in 9 patients in the placebo group vs 3 in the risedronate group.The authors report that there was no difference in the fall rate between the 2 groups, suggesting "risedronate may prevent hip fractures despite frequent falls."

该试验的主要终点为髋骨骨折发生率，在试验结束时，安慰剂组有9位病患发生髋骨骨折，而服用risedronate病患则有3位发生；作者表示，这两组病患之间发生跌倒的风险并无统计上显著差异，暗示risedronate可能预防髋骨骨折，但对於跌倒风险没有影响。
