In this paper, power limited relay network is considered. We take one example of the limited relay, i.e. energy harvesting (EH) relay to study the power planning problem. It is assumed that the EH process is stationary and periodical. A twoEH-relay network is considered for simplicity. Efficient power planning can maximize the sum capacity that can be achieved by the saved power of EH relays. S...

In this paper, we derive the exact symbol error probability (SEP) of cooperative systems using amplify and forward (AF) relaying and partial relay selectionwhen the different links are independent and non-identically distributed. In conventional relay selection, the selected relay offers the best instantaneous signal to noise ratio (SNR) of the relaying link (source-relay-destination). However,...

Relay feedback has a large variety of applications in control engineering. Several interesting phenomena occur in simple relay systems. In this paper, scalar linear systems with relay feedback are analyzed. It is shown that a limit cycle where part of the limit cycle consists of fast relay switchings can occur. This chattering is analyzed in detail and conditions for approximating it by a slidi...

In this paper we propose two throughput-oriented relay selection rules for multi-hop relay networks. Our rules can achieve higher throughput while maintaining reliability. We also adopt the total relay transmit power constraint to utilize transmit power more efficiently.

In this letter, we propose an efficient relay antenna selection algorithm for the amplify and forward (AF) two-way multipleinput multiple-output (MIMO) relay systems with analogue network coding (ANC). The proposed algorithm greedily selects the additional receivetransmit antenna pair that provides the maximum sum-rate. An iterative computation method is also designed to evaluate the sum-rate e...

In this paper, a two-phase protocol for relay-assisted spectrum sharing in cognitive relay network is proposed. The primary system comprises a transmitter-receiver pair (PT-PR) and a decode-and-forward relay (Relay), while the secondary system comprises a transmitter-receiver pair (ST-SR). In the proposed protocol, the Relay assists the transmissions of the primary users as well as the secondar...

647 Abstract— In this letter, non-regenerative Amplify-and-Forward (AF) relay systems based on half and full duplex schemes are investigated and their performance is analyzed and compared in terms of outage probability. Although the AF relay systems have been widely investigated in many previous literatures, most of them adopted a half duplex scheme due to hardware limitation and mathematical t...

This paper describes a node pair selection scheme in relay-aided multiple source multiple destination communication system based on stable marriage problem. A general case is assumed in which all of source, relay and destination nodes are equipped with multiantenna and carry out multistream transmission. Based on several metrics introduced from inter-node channel condition, the preference order...

In this paper, we study the transmit diversity of the cooperative relay system employing multiple-input multiple-output (MIMO) technology, especially for the Alamouti space-time block codes (STBC), over slow Rayleigh fading channel. The transmit diversity gain is achieved by STBC and cooperative technology. Maximum ratio combining (MRC) and maximum likelihood detection (MLD) are applied in the ...

In this paper, a 2-D geometric and adaptive relay node deployment method with polynomial-time complexity is proposed to reduce relay nodes for bridging all disconnected node pairs of a wireless sensor network (WSN). In this method, proper locations for placing relay nodes are discovered on a plane, which gives a much larger degree of freedom to compare with the traditional 1-D search algorithm....
