Hello,

I have been digging into this forum, finding *very good books* and other nice stuff. I'm planning to implement a WiMAX transmitter and receptor. For now, i should concentrate in transmitter.

I'm going to use VHDL mainly and open cores. So if you have any comments and if you want to discuss about it. I'd apreciate feedback.

Right now, i'm reviewing standards for 802.16, not sure which one to implement, i guess rev d would be the easiest one, what do you think?

Very Happy

P.S.- Yeah, probably 802.16e is very cool, but Scalable OFDMA is not yet an open core and standarization is not closed yet.

BTW, is this job done ? any helpful site ?

Yes - i have been reading about ofdm core. But tricky part i believe is how to place everything, all parts, together. BTW, i have downloaded a book that looks nice to me "Wireless Ofdm Systems: How to Make Them Work?" at http://www.edaboard.com/viewtopic.php?t=93421&highlight=802 and wimax standards, of course. Very Happy

It is a big team work to implement the WiMax, even if just the physical layer. You need people to work on the system architetcure design, system enginerrs to work on the algorithm development, fixed-point implementation of the modem, digital engineers to work on RTL coding and some HW engineer to work on the FPGA board, plus SW to control the modem function. At least 20-30 engineers to work on the real WiMAX. If you just work on a project for the class, you need select one function in the WiMAX modem, such as channel estimation, sync., frequency compensation, equalizer, Viterbi/Tubor/LDPC decoder.

True. But maybe using some IP cores, i could do an academic WiMAX approach.

I'm very interested in this project, so System.out, can you share your progress in this forum from time to time?

Sure, but i have not much time, so this is kind of stopped. I read some papers and articles... like http://www.iec.org/newsletter/oct06_1/analyst_1.html

I think i will not be doing much on this area on next months. But, i'd be good to concentrate all people interested together, and maybe that could end up on a WiMAX implementation... Smile

If you do it public, i'd like to see it. A good place to find some useful bits and that you can put your bits too is opencores.org.

Hi,
I am implementing WiMAX MAC.All the previous posts have been regarding PHY i suppose. Is anyone implementing MAC? I need some help.

20 Nov 2006 16:43 wimax ldpc decoder

in my project we are looking for:
1-FPGA kit with ethernet port interface

we began to read in the viterbi decoder as it is essential in the implementation

we should also read about OFDM technique

I am planning to port my design onto an FPGA board that I am having but tht will come at a later stage. Right now, I am concentrating on the implementation part. I really need to do some coding fast as I have to present my work in January. RIght now, I am implementing the downlink part using VHDL. I think we need to write some sort of a package for the implementation. Can anyone give any suggestions? And i need suggestions for MAC and not for PHY.

for the Physical layer implementation it is preferable to use DSPs instead of FPGA in case of graduation projects, FPGAs needs much development time and it is used in a corporate scale development teams.
Almost DSPs need less development time and use easier methods to develop on as using C-langauge.
You can male it much easeir by useing one of the TI DSPs that are intergrated with the mathworks software as the MATLAB and Simulink, this makes it easier.
For the MAC layer, it is mainly a software project that needs good programming skills espcially in C-langaue, also you can use one of the products of MATHWORKS which is STATEFLOW, a research team in Berkely used it to develop MAC layer of a new wireless system
This is on the development scale, you can shift your project in WiMAX implementation, by purchasing a WiMAX chip and interface it by a PCB to an Antenna and RF circuits and create a WiMAX CPE
you can find those chips as 6482 from TI and the atmel one

13 Oct 2008 17:35 implemetion of wimax projects

My scenario detailed further is listed below

1. Phy layer parameters should be kept constant (which i already have sent u)
2. Apply the MAC Layer over Physical layer
3. Mac layer is composed of three layers, the three layers are

* MAC Convergence Sublayer (responsible for header compression and SFID and DIC Identification)
* MAC Common part sublayer (responsible for assembly of MAC PDUs, ARQ Scheduling, MAC Management)
* MAC Security Sublayer (Responsible for encryption)
* Physical layer lies just below MAC Security sublayer

Now what we need to do is to keep all the parameter constant except common part sublayer, we need to change ARQ mechanism
we have to create 2 sceanario, in 1 case, What is BER when ARQ is is composed of ACK and Negative ACK, and what BW will be allocated for pay load in that case

2nd case scenario we have to show NACK is creating what BER and pay load (Data)'s bandwidth is increasing or not.

graph of BER\ BW ....

Can any one HELP ME??????
contact me ASAP

I need a help regarding my MS thesis. I have read few papers on Wimax Handover.And decided to work on wimax handover. But still i am not getting any idea on which specific topic i should work. Also i dont know how to use matlab. I have to learn it as well. Also want to know can we do wimax handover related work in Matlab? Please help me as i have short time. If you have any Handover code in Wimax? Thanks in advance.

03 Apr 2009 18:21 book on physical layer implementation on fpga

Hey I am shahid from karachi pakistan, studying in Final Year Electronics at NED University, Implementing IEEE 802.16-2004 Transmitter OFDM PHY on FPGA as my Final year project
Can any one tell me how many bursts can MAC transmit to PHY in a single frame ?
I asked this question because in implementing Randomizer, the burst # 2 and onwards are initialized with a vector including a Frame no..I have to build a virtual application to test my PHY by giving some user data, therefore plz do tell me then how many maximum no. of bursts can be transmitted in a single MAC frame.
Lookin for positive and urgent reply

Duh shahidbright Neutral

.... its a website. I want to know what are projects that are uploaded there. Are they like open source projects for implementation.

I'm only asking if there is useful stuff there, and what kind of useful stuff. If you know you can mention it here
