Abstract	This paper will deal with examining the performance of different link adaptation techniques for different service classes through land mobile satellite communication channels. There are different types of link adaptation techniques, like adaptive modulation and coding (AMC) or adaptive power allocation (APA), etc. Most of the today's link adaptation techniques exploit only the channel condition information to maximize bandwidth efficiency. However, taking into consideration the QoS information of services classes jointly with the channel condition information on the satellite link, an optimum usage of the resources can be reached. In this contribution it will be shown that data rate can be increased, and the delay can be decreased with this concept. However, considering land mobile satellite communication channels, the main part of the delay is caused by the propagation distance, so delay decreasing using AMC is not contributing significantly to the total delay. The paper will provide simulation results of spectral efficiency, and data rate of the proposed novel AMC, compared to the conventional AMC and of the proposed novel APA, compared to the conventional APA, based on measurement results of received power level of land mobile satellite connection operating at 1.54 GHz
