Cooperative communications

In this article, the authors introduce the "Cooperative WBANs" model, wherein sensors communicate directly with Access Points (APs) without a coordinator. They also present a power control algorithm for downlink data transmission from APs to sensors.

The research design was conducted using quantitative approaches. The major findings showed that the students’ proficiency in English did not satisfy the expectations of the stakeholders. Therefore, some practical solutions are given to improve the students’ level of use of English for tourism, including designing English tourism curriculum; building an e-learning system supports students’ self-studying; students’ opportunities to communicate in English, and the assessment processes; strengthen cooperation, learning and exchange with international enterprises.

The goal of the study is to determine ASEAN’s economic cooperation process and opportunities for Vietnamese businesses to invest in the ASEAN economic community in the period 1991 to 2020, and a vision to 2025-2030. To determine the investment trends of Vietnamese businesses in the AEC community according to specific fields, statistical and analytical techniques were used to conduct this research. An analysis of the study was presented in a table on the direct investment situation of Vietnamese enterprises to the AEC community according to each specific field in the period 1991 - 2020.

They study English to communicate with people from other countries where English is used as a native, second or just foreign language, to read English materials, or to pass the national secondary school exams. With such an important role, different aspects of the English language have been studied to gain different goals. In the area of crosscultural communication, speech acts have been widely and carefully studied since they are highly culturespecific.

The conclusion of this study, to overcome the lack of service of government apparatus in serving the community, the concept of service apparatus is harmonized with the vision of a mental revolution that emphasizes the work ethic and the spirit of mutual cooperation. The recommendation given is the existence of a synergistic social movement between the government and the community in routine activities starting from the scope of the family, school to the community.

When the sizes of end-user equipments are limited, the cooperative relay networks are recommended as promising virtual MIMO systems to improve the performance of wireless communication systems in literature. In this paper, we focus on performance analysis of twohop relay wireless networks using Decode-and-Forward (DF) scheme.

In this paper, we investigate the physical layer security technique of a cooperative communication network with a source node having multiple transmitting antennas, in which these antennas provide the most optimal antenna to increase security performance to a destination node via a relay node in the presence of an eavesdropper node.

In practice, fading channel coefficients are estimated imperfectly at receivers. In this paper, I propose and analyze a cooperative communication scheme under physical layer security with imperfect CSI. In this scheme, a source node transmits secure data to a destination node D with a help of a relay node against an eavesdropper node without direct links of source-destination and source-eavesdropper.

In this paper, an approach method to improve secrecy cooperation transmissions using combined signals is investigated in which data and jamming signals are combined at a source node based on power allocation strategy. The secrecy system performances are evaluated using asymptotic secrecy outage probabilities of end-to-end achievable secrecy rates over flat and block Rayleigh fading channels.
