... the users and BER per- formance can be included into OFDMA design considera- tions. For example, in Figure 6 we show the simulation re- sults for the BER-performance of an OFDMA system with 256 ... adaptive loading algorithms for both single- and multiuser OFDM systems. We show that the single-user system performance can be improved by suitable power loading and an algori...
