Description: The main reason for inaccuracies observed in location
estimation, imposed by the propagation conditions of the
wireless channel, is the Non Line Of Sight (NLOS) due to
transmitted signal blocking. Because of the NLOS, the first
TOA, which bears information related to the mobile
terminal position, suffers stronger attenuation than later
arrivals and therefore wrong timing information is
obtained yielding biased position estimation. Several
NLOS mitigation algorithms have been presented. One of
the most common approaches consists of correcting the
TOA measurements exploiting the fact that the variance of
the TOA measurements is significantly increased in NLOS
scenarios

Description: 这个程序可以计算给定点处的小区信号范围覆盖。-is program computes a map of visibility from a selected point on a topography. It has been written to help the search for radio relay best location. Because it considers only direct line of sight, it gives a good estimation for possible radio link for short distances only (less than 10 km), neglecting curvature of the Earth, Fresnel zone and atmospheric refraction on radio waves propagation. The program computes the relative elevation angle of the mask for each point (the angle is null or negative if the point is visible).
The function needs a digital elevation model Z and associated (X,Y) vectors or matrices of coordinates (same unit as Z), position of the point (X0,Y0), the antenna height H0 (for instance 4 m), and the hypothetic antenna height Ha on each topography points (for instance 3 m). When no output argument is given, the function plots a map of the results (color map of mask angles, and blank for visible points, see example screenshot).
The script is not fully optimize

Description: Rician fading is a radio propagation anomaly caused by partial cancellation of a radio signal by itself — the signal arrives at the receiver by two different paths, and at least one of the paths is changing (lengthening or shortening). Rician fading occurs when one of the paths, typically a line of sight signal, is much stronger than the others. In Rician fading, the amplitude gain is characterized by a Rician distribution.

Description: The effects of multipath include constructive and destructive interference, and phase shifting of the signal.
This causes Rayleigh fading, named after Lord Rayleigh. The standard statistical model of this gives a distribution known as the Rayleigh distribution.
Rayleigh fading with a strong line of sight content is said to have a Rician distribution, or to be Rician fading.

Description: 本实验设计了一个《导弹打飞机》的动画演示程序。建立地面坐标系，横轴x代表水平射程，纵轴y代表垂直高度，单位均为km。假设导弹的初始位置为(0，0)，飞机的初始位置为(20，0)，飞机在20km高度以1km/s的速度做水平匀速直线运动，导弹从地面发射，以2km/s的速度做等速运动，以追踪法对飞机进行打击，即导弹的速度方向始终沿着弹目视线且指向目标。-The experimental design was a " missile hit the aircraft," the animated demo. Establishment of ground coordinates, the horizontal axis x represents the level range, representative of the vertical height of the vertical axis y, units are km. Assuming the missile' s initial position is (0,0), the aircraft' s initial position (20.0), aircraft altitude at the 20km to 1km/s speed to do the level of uniform linear motion, the missile launched from the ground to 2km/s constant speed of movement to do in order to track the method of combat aircraft, the missile' s velocity is always along the direction of line of sight and the target missile to the target.

Description: Localization is one of the key techniques in wireless sensor network. The location estimation methods can be classified into target/source localization and node self-localization. In target localization, we mainly introduce the energy-based method. Then we investigate the node self-localization methods. Since the widespread adoption of the wireless sensor network, the localization methods are different in various applications. And there are several challenges in some special scenarios. In this paper, we present a comprehensive survey of these challenges: localization in non-line-of-sight, node selection criteria for localization in energy-constrained network, scheduling the sensor node to optimize the tradeoff between localization performance and energy consumption, cooperative node localization, and localization algorithm in heterogeneous network. Finally, we introduce the evaluation criteria for localization in wireless sensor network.
