Description: 基于OFDM的无线宽带系统仿真It contains mainly two parts, i.e. link-level simulator and system-level simulator.
Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx. Comparing the difference in tx/rx signal, the error rate can be found out. The output of the link-level simulator is the BLER/BER vs. SNR mapping table, that can be used for the system-level simulation.
System-level simulator focus on a multi-cell multi-user scenario. For the sake of simplicity, it takes the mapping table aquired in the link-level simulation, measure the actural SNR, and finds the corresponding error rate.

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: This M Code simulate the effects of clipping and filtering on PAPR reduction in OFDM-based wireless standard.Also the performance of BER versus SNR of original OFDM signals with PAPR reduction based on clipping and filtering schemes over AWGN channel is evaluated.
The simplest and most widely used technique of PAPR reduction is to basically clip the part of signals that are outside the allowed region.Clipping methode introduces both in band distortion and out of band radiation into OFDM signals which degrades the performance including the BER and spectral efficiency.Filtering can reduce out of band radiation after clipping although it can not reduce in-band radiation distortion.However, clipping may cause some peak regrowth so that the signal after clipping and filtering will exceed the clipping level at some point.To reduce peak regrowth a repeated filtering and clipping operation can be used to obtain a desirable PAPR at a cost of computational complexity increase.
