Simulated uncoded BER for different SNR values. Uncoded BER results obtained by simulation when CQI = 12 and SNR ranges from 11 to 31 dB for the interpolation factors I=1,2,3. Note that the channel model associated to the D2a link of the D2 scenario of the Winner Phase II Channel Models was applied. 95% confidence regions are provided. Corresponding relative error curves are plotted when the SNR is set to 21 dB, showing an excellent agreement. Note that for SNR values greater or equal than 31 dB, the BER curves are close to zero for speeds below 250 km/h; hence, the relative error curves do not provide much information.
