Abstract :
The adaptive modulation for the Generalized MultiCarrier (GMC) transmission is described, showing that non-orthogonality of the subcarriers affects the complexity of the adaptive techniques and the system performance. The mathematical derivation for the GMC channel capacity is presented. Since the straightforward formula is impractical from the implementation point of view, the efficient modifications of the Hughes-Hartogs algorithm are discussed. Simulation results are also included.
