Description: UWB脉冲设计与窄带干扰抑制
为了避免对频带内已有的窄带通信系统造成干扰，在进行波形设计时，如果能使UWB脉冲在干扰频带内的能量下降，即在窄带通信系统的工作频带内实现陷波，则可达到抑制窄带干扰的目的。-UWB pulse design and narrow-band interference suppression in order to avoid the narrow band communication systems has been caused by interference, in waveform design, if the UWB pulse can interfere with the band in the energy decline, that is, in the narrow-band communications system to achieve Notch can be inhibited to achieve the purpose of narrow-band interference.

Description: 端点检测是指用数字处理技术来找出语音信号中的各种段落（如音素、音节、词素、词等）的始点和终点的位置。语音段起止端点检测是语音分析、语音合成和语音识别中的一个必要环节。传统的端点检测方法是从wav文件中获取语音采样，将其分帧并计算短时能量和过零率参数，然后进行端点检测。这种工作方式被称为离线处理方法 ，无法实现语音信号的实时处理，对于语音信号分析具有一定的局限性。本文通过开发ActiveX控件，在MATLAB环境下将其嵌入到figure窗口中，以GUI程序的方式使用，实现语音信号端点检测的实时处理。-Endpoint detection is the use of digital processing techniques to identify the speech signals in a variety of paragraphs (such as phoneme, syllable, morpheme, word, etc.) the starting point and the end position. Speech endpoint detection is a paragraph beginning and end speech analysis, speech synthesis and speech recognition of a necessary link. Traditional endpoint detection method is to obtain from the wav file voice sampling, its sub-frame and calculate the short-term energy and zero-crossing rate parameters, and then proceed to endpoint detection. This work is called off-line approach can not achieve real-time speech signal processing, analysis of the speech signal has a certain limitations. In this paper, through the development of ActiveX controls, in the MATLAB environment to embedded figure window to use GUI program, the realization of speech signal processing real-time endpoint detection.

Description: Recent advances in wireless sensor networks have led to many new protocols specifically designed for sensor networks
where energy awareness is an essential consideration. Most of the attention, however, has been given to the
routing protocols since they might differ depending on the application and network architecture. This paper surveys
recent routing protocols for sensor networks and presents a classification for the various approaches pursued. The three
main categories explored in this paper are data-centric, hierarchical and location-based. Each routing protocol is described
and discussed under the appropriate category. Moreover, protocols using contemporary methodologies such as
network flow and quality of service modeling are also discussed. The paper concludes with open research issues
