Adaptive PSAM in Cross-Layer Combining of AMC and ARQ
Different schemes about power arrangement and spacing allocation of pilot symbols in cross-layer design are investigated in this paper. The purpose is to maximize the average spectral efficiency at the physical layer accounting for meeting the target package loss probability at the data link layer. The parameters associated with channel state information in cross-layer structure are modified by introducing the channel estimation error. The adaptive spacing is determined according to the channel characteristics and the power is adaptive arranged between the information symbols and pilot symbols by maximizing the modified average spectral efficiency.
