Decoding Neurotransmitter Switching: The Road Forward [PDF]
The 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 ...

Sequential slotted amplify-decode-and-forward [PDF]
2013 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 ...

Packet-reliability-based decode-and-forward distributed space-time shift keying [PDF]
, 2010 Motivated by the recent concept of Spatial Modulation (SM), we propose a novel Distributed Space-Time Shift Keying (D–STSK) scheme, where the SM concept is extended to include both the space and time dimensions for the sake of achieving a flexible ...

Exact and Approximated Outage Probability Analyses for Decode-and-Forward Relaying System Allowing Intra-link Errors [PDF]
, 2014 In this paper, we theoretically analyze the outage probability of decode-and-forward (DF) relaying system allowing intra-link errors (DF-IE), where the relay always forwards the decoder output to the destination regardless of whether errors are detected ...

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

An Efficient Partner Selection Method to Overcome the Interference Effect in Wireless Networks
IEEE Access, 2019 In this paper, through a mathematical analysis of the overall links capacity equation, we present an efficient partner selection criterion in a cooperative communication scheme with a time-varying fading channel and severe interference on the cooperative

PERFORMANCE ANALYSIS OF COOPERATION SCHEMES IN EAVESDROPPER ASSISTED RELAY CHANNEL [PDF]
ICTACT Journal on Communication Technology, 2014 The prominence of the wireless communication has been urging the monotonically increasing demand of security and privacy. In wireless systems, the notion of perfect secrecy of information with respect to illegitimate nodes can be ensured via physical ...

Robust Transceiver Design for IRS-Assisted Cascaded MIMO Communication Systems
Sensors, 2022 Intelligent reconfigurable surfaces (IRSs) have gained much attention due to their passive behavior that can be a successor to relays in many applications. However, traditional relay systems might still be a perfect choice when reliability and throughput

Multipair Two-Way DF Relaying With Cell-Free Massive MIMO
IEEE Open Journal of the Communications Society, 2021 We consider a two-way half-duplex decode-and-forward (DF) relaying system with multiple pairs of single-antenna users assisted by a cell-free (CF) massive multiple-input multiple-output (mMIMO) architecture with multiple-antenna access points (APs ...
