Hello all,

I am trying to get the receiver specs for a mobile WiMax tranceiver, in the standard, the only indication i found to receiver nonlinearity is given by the "adjacent and nonadjacent rejection at BER=10e-6 for 3 dB degradation C/I" numbers.
I really don't understand the term "for 3 dB degradation C/I"?, the standard doesn't give any details or power values for intermodulation tests in order to calculate IIP3 and IIP2, beside that, I can't find the required C/I ratio after the mixer in order to calculate oscilator phase noise.
can any body help?

Thank you very much

Re: questions in receiver nonlinearity specs for mobile WiMa

what is the frequency band of Wimax?What requirements are needed for PA in Wimax?
 

Re: questions in receiver nonlinearity specs for mobile WiMa

the mobile Wimax is defined in licensed bands: 2.3-2.x, 3.x GHz. PA must have a 45 dB dynamic range and a limitied relative constellation errors, -30 dB for 64-QAM-3/4 case. Beside a spectral flatness given by the standard and spectral mask left to local regulations.
