Decode-and-Forward Cooperative Protocol for Multiuser Communication Systems
Cooperative diversity is a promising solution for diversity gain, multiplexing gain and energy saving. This technique involves multiple users sharing resources in order to build a virtual antenna array in a distributed manner. In this paper, we propose multi-user cooperation strategy that allows multiple users to transmit their data simultaneously in decode-and-forward relaying systems. We cons...
متن کاملSoft Decode and Forward Improves Cooperative Communications
Mobile receivers can benefit from an increased spatial diversity through cooperation. Two relaying techniques are typically used : either Amplify and Forward (AF) or Decode and Forward (DF). This contribution presents a new technique which combines the main advantages of both AF and DF. This technique amounts to a DF scheme where all operations are performed in a soft-input soft-output fashion....
متن کاملCooperation Based on Decode-and-Forward Plus Cooperative Jamming for
We employed node cooperation in a cooperative wireless network to achieve physical layerbased security. The case of a source-destination pair that works with the assistance of multiple cooperating nodes in the presence of an eavesdropper was considered in this study to improve the performance of secure wireless communications. A novel cooperative scheme, called the decode-and-forward plus coope...
متن کاملDecode and Forward Cooperative Diversity for Modified SV Model Based UWB Communication System
Cooperative wireless networks have emerged as a major technology for future communication systems because cooperation in ad-hoc networks can save limited network resources. Cooperative techniques are the means to adopt the diversity, which is inherent in a wireless medium. While ultra-wideband (UWB) offers high information rates for wireless communication and sensor networks, the EIRP limits on...
متن کاملOptimization of relay placement and power allocation for decode-and-forward cooperative relaying over correlated shadowed fading channels
In this paper, we investigate the relay placement and power allocation for decode-and-forward (DF) cooperative relaying over correlated lognormal shadowed Rayleigh fading channels. Assuming that maximum-ratio combining is performed at the destination, we first derive an upper bound of symbol error rate (SER) withM-phase-shift keying (PSK) modulation. Then, three optimization problems are formul...
