Coding and Decoding for the Dynamic Decode and Forward Relay Protocol [PDF]
IEEE Transactions on Information Theory, 2008 We study the Dynamic Decode and Forward (DDF) protocol for a single half-duplex relay, single-antenna channel with quasi-static fading. The DDF protocol is well-known and has been analyzed in terms of the Diversity-Multiplexing Tradeoff (DMT) in the ...

Comparison of managed decode-and-forward scheme and common decode-and-forward scheme in cooperative communication systems [PDF]
Journal 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]
2011 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.
