A Cross Layer Optimization Based on Variable-Power AMC and ARQ for MIMO Systems
To improve spectrum efficiency (SE), the adaptive modulation and coding (AMC) and automatic repeat request (ARQ) scheme have been combined for MIMO systems. In this paper, we add variable power subject to power constraint in each AMC mode. We use KKT optimization algorithm to get the optimal transmit power and AMC mode boundaries. The numerical results show that the average SE is increased by a...
متن کاملThroughput Optimization for Mimo Systems Based on Cross-layer Design
Based on cross-layer design, an optimization method was proposed, which combined the adaptive modulation and coding with symbol rate at the physical layer, and the packet size and sub-packet number at the data link layer. The parameters were jointly optimized to maximize the MIMO system throughput in the Rayleigh fading channel. Numerical results reveal that the optimization method can be adapt...
متن کاملCross-layer design in AMC/ARQ-based wireless systems with cooperative relaying
Description: Recently, there have been a great deal of research efforts on cross-layer design in wireless networks (see, e.g., [1, 2, 3] and references therein). Furthermore, the past decades gave birth to a large number of innovative techniques at the physical layer (PHY) to overcome the impact of wireless fading channels and to support the diverse quality-of-service (QoS) requirements for het...

15 صفحه اولA Variable Structure Observer Based Control Design for a Class of Large scale MIMO Nonlinear Systems
This paper fully discusses how to design an observer based decentralized fuzzy adaptive controller for a class of large scale multivariable non-canonical nonlinear systems with unknown functions of subsystems’ states. On-line tuning mechanisms to adjust both the parameters of the direct adaptive controller and observer that guarantee the ultimately boundedness of both the tracking error and tha...
