In this paper, we propose a signal-aligned network coding (SNC) scheme for K-user time-varying multiple-input multiple-output (MIMO) interference channels with limited receiver cooperation. We assume that the receivers are connected to a central processor via cooperation links with individual limited capacities. Our SNC scheme determines the precoding matrices of the transmitters so that the tr...

Many situations in traffic involve multiple road users and can only be solved by successful cooperation. However, 30% of cooperation fail, which indicates that there is potential for improvement (Benmimoun et al., 2004). In this study, lane change manoeuvres were examined as a typical cooperative situation. order to improve cooperation, two ways enhancing tested. Firstly, head-up display was us...

This paper uses laboratory experiments to test the implications of the theory of repeated games on equilibrium payoffs and estimate strategies in an infinitely repeated prisoners’ dilemma game with imperfect public monitoring. We find that subjects’ payoffs (i) decrease as noise increases, and (ii) are lower than the theoretical maximum for low noise, but exceed it for high noise. Under the ass...

Signal detection performance in cognitive radio architecture is enhanced by the cooperation of sensing detectors if the fading and shadowing effects exist on the channel. A cooperative spectrum sensing technique in cognitive radio networks based on two-sample Kolmogorov-Smirnov test is proposed in this paper and proposed sensing scheme is examined under Rician fading channel. The performance of...

—In this paper, an improved multi-channel blind deconvolution algorithm for code division multiple access signals is proposed. Through minimizing the average squared crossoutput-channel-correlation, the proposed scheme achieves a better source separation performance for the linear convolved mixture system. Unlike most of the existing linear convolved mixture separation algorithms in the litera...

Within the FAIR SIS18 upgrade the data acquisition hardware as well as the concept for signal treatment of the Beam Position Monitoring system (BPM) were renovated. The former BPM system was based on the analog narrowband signal processing (see [1]). Since any information concerning an individual bunch is lost, observation in the turn-by-turn scale as well as tune measurement is impossible. Hen...

We develop a game-theoretic framework to investigate the effect of cooperation on the energy efficiency in wireless networks. We address two examples of network architectures, resembling ad-hoc network and network with central infrastructure node. Most present approaches address the issue of energy efficiency in communication networks by using complex algorithms to enforce cooperation in the ne...

The Device-to-Device (D2D) communication system is an important part of heterogeneous networks. It has great potential to improve spectrum efficiency, throughput and energy efficiency cooperation of multiple D2D users with the advantage of direct communication. When cooperating, D2D users expend extraordinary energy to relay data to other D2D users. Hence, the remaining energy of D2D users dete...

We propose a time-division uplink transmission scheme that is applicable to Long Term Evolution Advanced (LTE-A) systems and utilizes device-to-device (D2D) cooperation. We analyze its spectral efficiency and outage performance and show that compared to existing frequency-division schemes, the proposed scheme achieves the same or better spectral efficiency and outage performance while having si...
