In this paper, a compressed sensing (CS) based sparse channel estimation method is proposed for Unique Word (UW) Prefixed SC-FDE employed in sparse wireless channels, sparse channel estimation is formulated as a typical CS problem, and UW generation schemes are discussed, in addition, DantzigD selector is used to recover sparse channel impulse response (CIR) from limited number of noisy observation...
With the increasing technology and people living, many electronics products were discarded, which has been influence to environment, and now some studies of environment and product recovery have been emphasized with attention being given to societies and government .It is necessary to recovery household appliances, which take a large part in the waste electronics. In our country there is not a complete...
In order to improve the performance of existing multicast congestion control algorithm applied to wireless networks, in this paper, a TCP Vegas-like expert-controlled multicast congestion control mechanism (VEMCC) is proposed, which uses a recently proposed TCP Vegas throughput model. In VEMCC, the network congestion state is detected according to network relative queuing delay and packet loss; the...
With the people's attention to the product quality and the environmental protection consciousness enhancement, the reverse logistics start to cause continuously attention of people. More and more scholars research the origin, the concept, the classification of the reverse logistics. At present there are some researches of the reverse logistics, however, these researches are restricted only in the...

Reverse logistics is the means driving economic growth, and third-party reverse logistics (3PRL) is the important carrier to realize reverse logistics. So, the analysis on 3PRL and its provider selection is important. All of these third-party companies would benefit from a framework for decision making to determine if entry into this market is feasible for them. This paper firstly present the conception...
In the early of 1990s, reverse logistics was beginning to be widely concerned by some developed countries, as the government and consumers were more attached importance to environment. China had paid more attention to forward logistics, but there is little concern about reverse logistics. As China entered WTO, companies will be confronted with fierce competition. It is necessary for Chinese companies...
After many yearspsila research, circular economy is the best way to accomplish sustainable development. Recycling economy is based on enterprises, which is to recycle the domestic waste product. However, the reverse-logistics is one of the ways to reuse waste products. In china, the reverse logistics was paid attention. From the perspective of the society, good reverse logistics can be effective in...
Reverse logistics includes not only processing used products and processing returned merchandise due to damage, seasonal inventory, restock, recalls, and excess inventory but also reusable containers and returned packages. Good reverse logistics network can effectively make use of resource and energy, and take healthy balance between economy and environment. Reusable packaging reverse logistics network...
Two of the most significant problems of our era are the depletion of the natural energy and resources and the pollution caused from the disposal of waste end-of-life products. An effective reverse logistics (RL) operation can help organizations make good use of nature energy and resources and take healthy balance between economy and environment. Thereby RL has emerged as one of the most rapidly evolving...
With the rapid development of manufacturing, it has brought about numerous material welfare to human society as well as many problems of resources and environment. Under the background of trying for the harmonious development of economics and environment, green supply chain management (GrSCM) emerged as the time required, which was considered as a mode of sustainable development of the enterprises...
