In this thesis, we begin by investigating the fading characteristics of OFDM subcarriers and discover that some OFDM channels exhibit non-uniform subcar-rier fading distributions. For such channels, we propose a novel adaptive modula-tion scheme to achieve better spectral efficiency, transmission po...
