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). Platform: |
