Joint resource optimization in spectrum sharing decode and forward relaying networks. [PDF]

open access: yesPLoS ONE, 2021
This paper proposes an adaptive power allocation and subcarrier pairing algorithm for orthogonal frequency division multiplexing based decode and forward cognitive radio networks, where primary and secondary users achieve spectrum sharing in the same ...

Partial Soft Decode and Forward [PDF]

open access: yes2011 IEEE Vehicular Technology Conference (VTC Fall), 2011
Soft Decode and Forward (SDF) cooperation techniques have been shown to improve the performance of Distributed Turbo Coding (DTC) schemes, in which the Source Node (SN) and Relay Node (RN) employ convolutional codes, while the Destination Node (DN) employs a turbo decoder.

Comparison of managed decode-and-forward scheme and common decode-and-forward scheme in cooperative communication systems [PDF]

open access: yesJournal of Intelligent Procedures in Electrical Technology, 2015
In this paper, the symbol error rate of M-PSK modulation in managed relay scheme is computed. In the conventional technique, the relay always decodes the received signal and re-sends it to the destination. In the destination, the two copies of the signal

Decoding Neurotransmitter Switching: The Road Forward [PDF]

open access: yesThe Journal of Neuroscience, 2020
Neurotransmitter switching is a form of brain plasticity in which an environmental stimulus causes neurons to replace one neurotransmitter with another, often resulting in changes in behavior. This raises the possibility of applying a specific environmental stimulus to induce a switch that can enhance a desirable behavior or ameliorate symptoms of a ...

A Two-Hop mmWave MIMO NR-Relay Nodes to Enhance the Average System Throughput and BER in Outdoor-to-Indoor Environments

open access: yesSensors, 2021
Millimeter-Wave (mmWave) bands are receiving enormous attention in 5G mobile communications, due to the capability to provide a multi-gigabit transmission rate. In this paper, a two-hop architecture for 5G communications with the capacity to support high

Sequential slotted amplify-decode-and-forward [PDF]

open access: yes2013 IEEE Wireless Communications and Networking Conference (WCNC), 2013
In this paper, we propose a novel slotted hybrid cooperative protocol named the sequential slotted amplify-decode-and-forward (SADF) protocol and evaluate its performance in terms of diversity-multiplexing trade-off (DMT). The relays between the source and destination are divided into two different groups and each relay either amplifies or decodes the ...

On relay selection for decode-and-forward relaying [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2009
In this letter, we consider a multi-relay network operating in decode-and-forward mode. We propose a novel relay selection method with a low implementation complexity. Unlike the competing schemes, it requires neither error detection methods at relay nodes nor feedback information at the source.
