I am currently brainstorming ideas on how to create a bit error rate (BER) measurement system across an ethernet communications link. What I have been thinking of doing is, using shift registers and some logic gates to create a pseudo-random bit sequence on the transmitting side. This sequence will then be sent across the ethernet via UDP (not TCP since I want errors to occur at other end), and received and compared with a locally generated PRBS. I just wanted to know what kind of difficulties might I face (such as synchronization issues, protocol issues, feasibility, etc.) and if there may be a better method to accomplishing such a test system from someone who may have had experience with this. The point of this is to test a wireless 802.11a/g network injected w/ noise. Any suggestions would be much appreciated.
Thanks,
