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 ...

Multilevel Coding for the Full-Duplex Decode-Compress-Forward Relay Channel

open access: yesEntropy, 2017
The Decode-Compress-Forward (DCF) is a generalization of Decode-Forward (DF) and Compress-Forward (CF). This paper investigates conditions under which DCF offers gains over DF and CF, addresses the problem of coded modulation for DCF, and evaluates the ...

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

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.

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 ...
