摘要：
The rapid development of the information-exchange networks accelerates the consumption of resources and energy. For future green communications, the integration of many conventional communication systems is necessary, where the optimization of the component elements in the communication integrated systems realizes energy-savings. In this paper, integrated physical-layer and cross-layer communication coding systems are reviewed, where the physical-layer design focuses on coded modulation and the cross-layer design focuses on the joint source-channel coding scheme and joint channel physical-layer network coding scheme. The characteristics of the integrated systems are analyzed using the extrinsic information transfer algorithm. Taking the re-design of the protograph low-density parity-check codes as an example, different design principles for various integrated systems are discussed, showing the necessity and significance of optimization for component elements in integrated coding systems for green communications.
