Hello everyone,
I just have a simple question. We all know that there is an error in the estimation of the SNR at the receiver, which will be sent back to the transmitter and hence lead to an over estimation or underesatimation of the SNR, which will make the transmitter choose the wrong constellation size and coding rate. My question here is what is the range of the allowable error in the estimation in SNR (in DB), and if someone can provide a code to plot the throughput or the spectral efficiency Vs SNR in Adaptive Coding and Modulation (AWGN or Rayleig channel), I would be extremly greatful.
Waiting for your smart answers guys.
Thanks in advance xx
