Hi,
I read an article on WiMax RF receiver sensitivity. It first gave SNR (2.9 dB) for QPSK signal. Receiver NF is 5.5 dB, implementation loss 1 dB. Then, it said that for a 10-MHz desired channel, the QPSK sensitivity is –94.6 dBm.
Here is the link: https://www.eetimes.com/document.asp?doc_id=1272474
I would like to know how to get '-94.6 dBm. Any one can help me?
Thanks,

I just get my result for 10 MHz bandwidth. It is -94.43 dBm.
For the result on 3.5 MHz width, 5.5 dB NF, I get -102.89 dBm. I don't know why the author had -103.1 dBm. Which one is correct?
