what is the relation between the BER and frequency

[So.nia]

Hello all;

how can i define the BER (Bits Error Rate ) fom the frequency

bests

Hello,

I think BER depends on the modulation scheme, and S/N ratio (or Bit energy over spectral noise density ratio, Eb/No). I don't see a direct relation with frequency, so maybe you can clarify your question.

Increasing frequency decreases the eye open time, but you
need to know the transition time and signal jitter to do any
useful analysis; BER is the statistics of how often an extreme
jitter event violates the useful eye (period - risetime - falltime).

acually i need to calculate sNR and i know the relation between the SNR and BER but my only data is the FREQUENCy

 

[dick_freebird]

If you don't have at least one or two BER:freq data pairs
then I think you're short on data. Frequency alone does
not paint a complete picture.

I will ask my question differently !
what the BER for a frequency (or speed data rate) between 10 and 15 Gb/s

BER don't have any direct relation with frequency but usually as the frequency increases the BER also increases (in wireless) because of Rayleigh fading (higher freq need Line of sight) etc.
