Abstract

Orthogonal Frequency Division Multiplexing is often treated as the promising technique for next wireless or wired communication systems. Beside its great advantages, orthogonal frequency division multiplexing has also some weaknesses, such as high out-of-band emission or high peak-to-average power ratio, which become the basis for investigation on new transmission techniques. In this paper the application of the so-called generalized multicarrier (GMC) signaling is considered as a good solution for application in future systems, especially for cognitive-radio applications. It is characterized by high flexibility and adaptability of its parameters, thus allowing for e.g. low out-of-band emission. In this work the possibilities of application of link adaptation techniques have been analyzed, with the particular attention put on the mercury-waterfilling principle. Two approaches of application of this procedure in GMC systems have been proposed and analyzed by means of computer simulations.
