A 802.16d System (Comments on English)

A WiMAX System Simulation

Description

A WiMAX simulation where you can define the number of OFDM symbols to simulate, type of channel (SUI 1-6 or AWGN Channel), lots of BW and different values for cyclic prefix. You are also able to select 4 different modulations same as IEEE 802.16d.

There is no Simulink needed. Everything is code. Translate into English by Faisal Madani.

All the coding stages from the Standard IEEE 802.16 are also simulated ( Randomize, RS Code, CC and interleaving)

To run the program type "wimax"

• Acknowledgements: This submission has inspired the following:; wimax physical layer simulation
• MATLAB release: MATLAB 7 (R14)

Good files,呵呵

[Zhong]

nice，thanks

[Ivan Jimenez]

I would like to get the power spectral density from your files. What file would you recomend me to modify. Thank You. By the way, your programs are really good.

[Ivan Jimenez]

There is a slight mistake in your "draw.m" file. Where you used the function "grids on", MATLAB does not recognize it because it is "grid on". Otherwise, everything lookis fine.

But ,your code run so long time ...please help me make it faster

"Please enter your choice" ... If choice =1 ,sumilink is run, not error and choise =2 or 3 or 4 or 5 ,simulink is error

Hepl me!

Dear sire
Your programme is perfect, I have to say well done to you, BUT there is one problem, which is the running time is too long? How can I manage it to make it quicker? Help me to sort it out please, Many thanks in advance.
