在无线局域网中,主要的性能除了吞吐量之外,另外一项比较受人关注的就是覆盖范围,而为了计算Wi-Fi的覆盖范围,我们首先要梳理其链路模型。本文我们基于基本的自由空间传输损耗模型(Free-space path loss),对802.11中的链路模型进行分析。 注:在该文之后,我们会基于在理解链路模型的基础上,继续讨论如何计算无线的覆盖范...
The free space path loss in decibels is approximately 197.5 dB. Alternatively, you can compute the loss directly from Loss = 2*pow2db((4*pi*tgtrng/lambda)^2) Loss = 197.4635 Propagate Linear FM Pulse Waveform to Target and Back Construct a linear FM pulse waveform of 50 ms duration wit...

The Wideband Free Space Channel block propagates the signal from one point to another in space. The block models propagation time, free space propagation loss and Doppler shift. The block assumes that the propagation speed is much greater than the target or array speed in which case the stop-...
The phased.FreeSpace System object models narrowband signal propagation from one point to another in a free-space environment.
Free Space Path Loss in dB Assume a transmitter is located at(1000,250,10)in the global coordinate system. Assume a target is located at(3000,750,20). The transmitter operates at 1 GHz. Determine the free space path loss in decibels for a narrowband signal propagating to and from the ta...
They are then subsequently analyzed by the OFDM analyzer for offline processing by MATLAB. Fig. 5: Combined fiber-FSO (FSO, free-space optical) communication systems. a Framework of combined fiber/FSO communication systems at MMW (MMW, millimeter-wave)/sub-THz (sub-THz, sub-terahertz) ...
The offset angle splits the interference pattern into three separated peaks in the Fourier space. Analyzing these peaks allows a quantitative phase map of the sample to be constructed, as described below. Image analysis The interference patterns, or holograms, were analyzed using the software MATLAB...

If only cells at the surface of a tumor are clonogenic (surface growth) the fraction of cell divisions that result in clonogenic cells depends on the available space at the tumors surface, and hence on the size of a tumor. Under the assumption of spherical tumor growth, it can be shown ...
