In [12] it is observed that for OFDMA systems implementing a family of M-QAM modulations (as those described in =-=[10]-=-) with some BER target, the AWGN capacity formula (1) should be replaced by ( C = w log2 1 + SNR ) Γ where Γ = − ln (5 × BER) /1.5 (which is larger than 1 for BER < e−1.5 /5 ≃ 0.0446).

The assumption that the fading is constant over a time slot may be replaced by the less restrictive assumption that the fading is ergodic and perfectly known by the receiver (see =-=[6]-=-). In what follows we analyze the three time scales of our model described in Section II-A. III. INFORMATION THEORY We assume that the users don’t move at the considered time scale. Consider a given u... |

It is interesting to couple this with the account of the speed effect at the queueing theory time scale in =-=[3]-=- which have shown that mobility ameliorates performance.
