Doppler
A signal is transmitted using a carrier frequency of 900 MHz. It is
transmitted through a multipath channel which can be modelled as Rayleigh
fading. Assumingthe Dopper spread as 10Hz and the number of multipaths as
10, generate the Rayleigh faded signal. Compute the outage rate (the
probability of the signal falls below certain rate, say ?10 dB) of the
signal.
Using MATLAB, demonstrate the path loss as a function of loss parameter
for distances ranging from 2 km to 40 km. Calculate the power loss in dB

运动目标的检测是视频处理过程中后续跟踪技术的基础,其检测结果的好坏直接关系到能否跟踪到运动目标及跟踪准确度问题。运动目标的检测就是从机器视觉系统获取的序列图像中把前景,运动,目标分割提取出来的过程。本文描述了机器视觉中运动目标检测的主要方法?介绍了其中背景减除法的几种典型算法的原理、特点、背景差分法的基本流程?主要包括四个步骤为,预处理、背景建模、目标检测、后处理。然后在matlab环境下运用背景减除算法完成了视频中运动目标的检测,并对检测结果图像进一步处理.(Moving target detection is a follow up video processing technology based on the test results is directly related to the ability to track moving targets and tracking accuracy. Moving target detection prospects, movement, object segmentation extracted from the sequence of images acquired by the machine vision system. This paper describes the main method of moving target detection machine vision ? introduced the principle of which several typical algorithms for background subtraction method, the basic flow characteristics, background difference method ? mainly includes four steps, preprocessing, background modeling target detection, post-processing. Use background subtraction algorithm in Matlab environment complete video moving target detection, and detection results of images for further processing.)

CurveLab-2.1.2
CurveLab is a collection of Matlab and C++ programs for the Fast Discrete Curvelet
Transform in two and three dimensions.
For the 2d curvelet transform, the software package includes two distinct implementations:
the wrapping-based transform and the transform using unequally-spaced fast Fourier trans-
form (USFFT). Both variants are based on the Curvelet transform as described in ‘New
Tight Frames of Curvelets and Optimal Representations of Objects with Piecewise C2Sin-
gularities’, Comm. Pure Appl. Math. 57 (2004) 219-266. The implementation is also
discussed in detail in ‘Fast Discrete Curvelet Transforms’, Multiscale Model. Simul. 5
(2006), no. 3, 861-899. We advise users to become familiar with these references.
The two implementations diff er by the choice of spatial grid used to translate curvelets at
each scale and angle.(CurveLab is a collection of Matlab and C++ programs for the Fast Discrete Curvelet Transform in two and three dimensions.
