Cooperative communication in wireless sensor network (WSN) explores the energy efficient wireless communication schemes between multiple sensors and data gathering node (DGN) by exploiting multiple input multiple output (MIMO) and multiple input single output (MISO) configurations. In this paper, an energy efficient cooperative MIMO (C-MIMO) technique is proposed where low density parity check ...

In wireless sensor networks (WSNs), cooperative communication represents a potential candidate to combat the effects of channel fading by exploiting diversity gain achieved via cooperation among the relays nodes. However, for the energy-constrained WSN, to what extent cooperative communication can save energy consumption for a successful packet transmission is still unknown. Energy efficiency o...

Cooperative communication is starting to attract substantial research attention in quantum information theory. However, given a specific network, it is still unknown whether quantum cooperative communication can be successfully performed. In this paper,we investigate network coding for quantumcooperativemulticast (QCM) over the classic butterfly network. A very reasonable definition of QCM is f...

Orthogonal frequency division multiplexing (OFDM) is becoming the chosen modulation technique for wireless communications. OFDM can provide high data rate, large spectrum efficiency with sufficient robustness to radio channel impairments. Cooperative diversity in wireless communication is a promising technique to mitigate multipath fading, which results in a fluctuation in the amplitude of the ...

Reconfigurable intelligent surface (RIS) provides a promising way to build programmable wireless transmission environments. Owing the massive number of controllable reflecting elements on surface, RIS is capable providing considerable passive beamforming gains. At present, most related works mainly consider modeling, design, performance analysis and optimization single-RIS-assisted systems. Alt...
