Abstract

This contribution focuses on the optimization of the parameters for the services in a sub-band based OFDM system using AMC and power control at the physical layer and having a finite-length queue at the data link layer. Since the length of the queue at the data link is not infinite, the packets are possible to be dropped before their transmission at the physical layer, and on the contrary, there may be inadequate packets in the queue for the physical layer to transmit. The dropping rate and the error rate will jointly affect the packet loss rate. It is necessary to consider the parameters in the physical layer and high layers to minimize the packet loss rate of the wireless systems, which will lead to an improved spectral efficiency and high data rate. Numerical results are presented to show the relationships between the performances and various parameters.
