Presently I have designed a 802.11b VOIP.
But the TX PER is not good enough even I increase the transmiting power.
All the data (11, 5.5, 2, 1) except 1Mbps can not pass the test at 1000 packets size after 500 times transmission.
Checking the EVM, I found the EVM is not good enough.
Since our system is one chip solution, all PA, SW, LNA are all built-in together.
Hoe can improve EVM?
Are there any factors affecting TX PER?
