File Information

LS-WOS V1.1 (Link & System-Level Wireless OFDM System Simulator Version 1 update 1)

This is the first time this simulator is published. We have tried to verify this simulator many times, however, there might still be some bugs. Please let us know if you found them. Thanks a lot.

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.

Link-level simulator support SISO, 1 by x MRC, 2 by 1 STBC/SFBC, 2 by 2 Alamouti, x by 1 Antenna selection, x by y antenna selection.
System-level simulator, currently support only SISO and 1 by 2 MRC.

To start with, go into the folder sys_link_simu, and excute the following commond from matlab:


where a is the link adaptation interval, in terms of No. of OFDM frames. b is the power adaptation interval. e.g. a = b = 1.

results will be saved in sys_link_result folder.

Detained manual will be provided later in wikipedia. The link is:

For questions in how to use this simulator, or suggestions, please use this wiki page, you can add you questions there, and we'll try to anser as soon as possible.

Update information:
1. Includes one script for a basic OFDM system, link-level evaluation. So that users can easily get started with the simulator. The script is under the folder 'link_lv_simu', with name 'yy_simpleOFDM.m';

Go inside this folder, and run the above mentioned script, in around 1 minute, you'll see a figure with all the important result (Coded/Uncoded BER, BLER & Spectral Efficiency).

2. Bug fixed in comm_funcs/channelgenerator2.m, for AWGN channel case.

Required Products Communications System Toolbox
MATLAB release MATLAB 7.2 (R2006a)
Other requirements DOESN'T work with matlab version earlier than 7.1 Takes at least several hours for the system-level simulation.

Hi Dear..
Thnx alot & great job, me too I'm working on STBC with LDPC in WiMax ..but till now i'm searching.....hope everyone have a little about my field me ..& i'll be very thankful
