I have a ML605 dev board with a fmcomms1-ebz board. I want to decode 802.11 a/b/g type wireless. Can this be done and if so where would I get the FPGA IP for doing to decoding?
Yes, this can be done. In fact, I am working on such a capability. But it is a lot of work, and I just starting with the FMCOMMS. Right now, I am concentrating on packet detect, preamble decoding, etc.
That's what I need to do too. Any hints would be helpful.
Sine you are interested in such a capability (with a commercial goal, I guess (i went through the Forensic wbe site)), and I am working on this capability (with a goal to develop even more extensive capabilities, applied to commercial markets), let's discuss about cooperation possibilities. On my side, I am more or less freelance, with access to a lot of development tool (I have a part-time job in the EE department at Laval University, quebec-city), and I have near 30-years experience in advanced DSP and FPGA development execution and management. For example, I managed the development of an FPGA-based GSM stack; I was also managing defense-related projects.

Please provide me your direct email, and we can exchange further.

If FMCOMMS is suitable for 802.11b/g, could we say that FMCOMMS supports TDD ? This point is missing from all the documents I can find online
Also, from the link http://www.analog.com/en/evaluation/eval-fmcomms/eb.html#DOCUMENTATION
the channel bandwidth is 125MHz. However, I notice that the bandwidth turns to be 200MHz @http://www.analog.com/static/imported-files/overviews/FMC-Communications_Product_Highlight.pdf
Which one is the right bandwidth, is the bandwidth fixed or programmable ?
I read this link before, it can only link me to wiki .....
The wiki is dynamic - I updated things after you asked the question.
Thanks. Could the bandwidth be changed by software (I need a much smaller bandwidth)? and does this FMC board supports TDD?
Yes - Either:
- Decimation can be done inside the FPGA
- Clocks can be slowed down.
