I need sample VHDL codes

Dear all,

I need some VHDL sample codes for the common communication systems modulators and demodulators .. such as QPSK, OQPSK, BFSK, ... and so on..

Can someone tell me where from? Or upload some?

Thanks ,
Ahmad,

most codes are IP
see this link, it'll help you to start

https://www.comblock.com/download.htm

Thank you very much, but i think that link doesn't provide free IPs but sell them, and doesn't provide the details of the design or the VHDL code of them.. Am I correct?

I need another much simple thing, I want the block diagram of each mod/demod schems such as QPSK, OFDM, OQPSK,...
I want only block diagrams, if there's simple explaination for each of them, this would be nice.
I need them for a trainee in our company to try to implement via HDL language.

Thank you for concern,
Ahmad,

there are detailed info
not to the very minute details, but it's great as a starter

for example, for "BPSK/QPSK/OQPSK MODULATOR" u can see this link:

i hope that's what you need

I'm tired of seeing posts like this, please give me this, please give me that ..etc etc. Why doesn't your company go and buy them like most other companies in this business. The companies who spend a lot of time and resources developing these systems employ people like you and me, so if they are hacked or got illegally, then those jobs are in jeopardy.

In my opinion, you have two choices...develop them yourselves (loads of time and effort) or pay for them (get them immediately, which will be probably much less expensive in the long term). If you can't do either, then your company is very weak and you had probably better look for another job.

Hi Ahmad,

It was not my intention to post a "cruel" post so apologies for that.

How would you feel someone starts asking for what your company makes for nothing. The way I see it, there are people who want something for nothing. For most decent IP or it takes time and effort. I see all these scanned books on this forum. You are denying the author his rightful compensation for his work. I just don't believe it should be given away.
