... achievable outage capacity for α- OFDM#3 is less than the outage capacity for α-OFDM#1; Lemma 1 provides an upper bound on the achievable capacity for α-OFDM#3. As a consequence, if an OFDM system ... scenarios. In terms of performance in block fading channels, the consequence of Lemma 1 is that the outage capacity of α- OFDM#1 equals the outage capacity of the class...
