Diversity Combining for Cooperative Communications
نویسندگان
چکیده
The benefits of cooperative communications in terms of link reliability and coverage extension are becoming more and more known to the telecommunication community, and have attracted the interest of both academia and industry in the last few years. Through the utilization of spatially distributed single-antenna terminals, cooperative communications are designed to achieve the beneficial effects of diversity in future networks without the need for employing multiple antennas at either the transmitter or the receiver end. As has been demonstrated in many research works in this area, cooperating terminals AbstrAct

Implementation of Co-Operative Diversity and Space Time Coding In Wireless Networks
A Wireless Ad-hoc network is an autonomous and self-organizing network without any centralized controller. Cooperative communication is a technique used to increase the reliability and the quality of service (QoS), coverage area range. Space time coding and spatial diversity schemes enhances the performance of the wireless networks. Such networks can be used in military communications and have ...
متن کاملCooperative Diversity in Cognitive Relay Networks using Different Coding Techniques
Cognitive radios (CR) represent new technique that can effectively improve the spectrum efficiency of future wireless networks. In this paper, the problem of cooperative relay in CR networks will be investigated for further improve network performance. A scenario in which a secondary transmitter can communicate with a secondary receiver via a direct communication link or a relay channel will be...
متن کاملOn Throughput Performance of Decode and Forward Cooperative Relaying with Packet Combining and Arq
Cooperative Diversity can be used by wireless nodes to take the benefit of broadcast nature and inherent spatial diversity of wireless channel to relay messages for each others. This helps to propagate redundant signals over multiple paths, which can be used to combat the channel noise and fading effects. We investigate the use of packet combining in cooperative diversity scenario. In our appro...
متن کاملCooperative communications for sleep monitoring in wireless body area networks
This paper investigates the performance of cooperative receive diversity, for the wireless body area network (WBAN) radio channel, compliant with the IEEE 802.15.6 Standard, in the case of monitoring a sleeping person. Extensive WBAN measurements near the 2.4 GHz ISM band were used. Up to 7 dB and 20% improvement for two-hop communications with the use of relays are empirically demonstrated wit...
متن کاملPerformance of Cooperative Diversity in Cognitive Relay Networks
In a network with dynamic spectrum access, secondary users equipped with frequency-agile cognitive radios communicate with one another via spectrum that is not being used by the primary users or licensed users of the spectrum . We consider a scenario in which a secondary transmitter can communicate with a secondary receiver via a direct communication link or a relay channel. Cooperative relay c...
