It's very hard to have a future for this technology, mostly because of standart's lacks and high power consumption for mobile versions. Practically, it's hard to make to work several subscribers and base stations from different vendors. Even if they all are certified. And also there is a big...
In WiMAX, you can transfer your VoIP data throught air link with diffrent levels of QoS. Those levels depend of a settings of MAC level.
If you want to use g711, g726 or (g729 or g723 without a silence suppression), you should utilise UGS type of traffic. If you want to g729 or g723 with a...
It should be better to use EDF algorithm for scheduling UGS and rtPS service flows and WFQ algorithm for scheduling nrtPS and BE service flows. Any management connection should be also sheduled with EDF algorithm.
Hi,
For understanding, how you can implement the WiMAX RS coder, you should use the following script on Matlab:
y = ['D4';'BA';'A1';'12';'F2';'74';'96';'30';'27';'D4';'88';'9C';'96';'E3';'A9';'52';'B3';'15';'AB';'FD';'92';'53';'07';'32';'C0';'62';'48';'F0';'19';'22';'E0';'91';'62';'1A';'C1']...
mac layer in simulink
For more detailed descriptions of EDF and WFQ algorithms you should read the following book - "Scheduling in Real-Time Systems" by Francis Cottet, Joelle Delacroix, Claude Kaiser, Zoubir Mammeri.
One useful practical exapmle of using WFQ algorithm is described in a book...
smartbits mac layer
For PHY simulation, it is better to use both Matlab and Simulink, because Matlab will help you with randomizer and interleaver (you sould write some m scripts) and you can use Simulink with RS and CC blocks (but i didn't use Simulink).
mac layer source code
For full simulation of MAC level, i think, it should be better to write a simulation program on C or C++, because there are a lot of structures, like a QoS parameters, Service Flows parameters, MAC management packet's data etc. As for me, it's too difficult to implement...
Re: labview CCS
I had similary problem some times ago, but i haven't had solution yet.
I think, you should try to use ActiveX Container and insert ActiveX Control like a RTDX Channel Viewer, Configuration or Diagnostic control. Also, you should try to write your own DLL library and use it with...

c++ windows interrupt
I've written driver for RTC clock, but only for Windows 95/98 (Vxd and WDM). I tried to run WDM driver under Windows 2000/XP, but it crashed because Win2000 don't share IRQ8. I heared about cathing this interrupt in Ring 0 mode, but system worked unstable after that.
