A novel algorithm with a new adaptive modulation form to improve the performance of OFDM for 4G systems

This paper tries to present a new form of adaptive modulation which has the ability of using the high order modulation schemes such as 256-QAM and 128-QAM at low SNR values such as 2, 4 and 8 dB in order to enhance the data rate without degrading the SER performance especially at low SNR values. Thi...
