Study of a novel adaptive bit loading and power control scheme for OFDM systems
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...
