Description: 很好的OFDM的基于MATLAB的仿真程序包，且包含了最终结果图.-montecarlo
type montecarlo in the command window and wait for a long time..
_simulation of the complete OFDM system.
_use of a very large file in order to get probabilities.
_loop over different value of the noise.
_compute the SNR for each value of the noise.
_provide the SNR/BER plot.
if you are in a rush : simulation_system !!
go into the right folder and type simulation_system in the command window.
_then type the value of the noise power (range = [-20,10])
_the function provides the channel estimation, the bit allocation,
and a plot illustrating the errors.
_this is a fast function (less pilot, no synchronization, small file).

Description: Wireless Sensor Networks have been proposed for a multitude of
location-dependent applications. For such systems, the cost and
limitations of the hardware on sensing nodes prevent the use of
range-based localization schemes that depend on absolute pointto-
point distance estimates. Because coarse accuracy is sufficient
for most sensor network applications, solutions in range-free
localization are being pursued as a cost-effective alternative to
more expensive range-based approaches.
