Degrees of freedom in adaptive modulation a unified view.

Degrees of freedom in adaptive modulation a unified view.

We examine adaptive modulation schemes for flat-fading channels where the data rate, transmit power, and instantaneous BER are varied to maximize spectral efficiency, subject to an average power and BER constraint. Both continuous-rate and discrete-rate adaptation are considered, as well as average...
