Description: In this paper, a two-dimensional (2-D) transverse
magnetic (TM) mode finite difference time domain (FDTD)
method is used to simulate the indoor radio wave propagation
and model the indoor ultra wideband (UWB) channel. The
modulated Gaussian pulse, which is satisfied the UWB signal
definition and Federal Communications Commission (FCC) indoor
limit spectral mask, is used as the UWB excitation signal.

Description: 实现功能简述:verilog写的
本模块主要功能是产生一个确定时钟周期长度（最长为256个时钟周期）的脉冲信号，可以自己设定脉冲长度，输出的脉冲信号与时钟上升沿同步
脉冲宽度 = pulsewide + 1 时钟周期
输入一个启动信号后，可以产生一个固定时钟周期长度的脉冲信号，与启动信号的长短无关！脉冲宽度可调！-Functional Description of the module to achieve the main function is to produce a certain clock cycle length (up to 256 clock cycles) of the pulse signal can be set for pulse length, the output pulse signal synchronous with the clock rising edge pulse width = pulsewide+ 1 clock cycle enter a start signal, can produce a fixed clock cycle, pulse length, the length of the signal has nothing to do with the start! Pulse width adjustable!

Description: Ultrasound Speckle Reduction Using Coded Excitation and Pulse Compression
Ultrasound images are riddled with system dependent imperfections called speckle (multiplicative noise). In ultrasonic imaging, detection of small lesions could be difficult because the effects of speckle may mask the visibility of these small targets. Therefore, the purpose of this project is to decrease speckle while maintaining some of the key salient features in the image. Images of tissue-mimicking phantoms will be created using Field II [1-2] in MATLAB (Natick, MA). Image quality metrics such as speckle signal-to-noise ratio (sSNR) [3] and contrast-to-noise ratio (CNR) [4] will be used to quantify improvements in image quality after various despeckling filters have been applied.
