We propose a novel cooperative diversity using multilevel coded modulation which can perform with arbitrary number of cooperative nodes. The proposed multilevel coded cooperation makes use of a signal superposition, which is one form of analog network coding techniques. Due to the ability and flexibility of a multilevel coded modulation, the proposed multilevel coded cooperation can outperform not...
This paper proposes a new coded cooperation protocol based on multilevel coded modulation for the case when the number of cooperative nodes is arbitrary. If the number of cooperative nodes is N, the proposed system makes a cooperative diversity with the multilevel coded 2N-PAM. Multilevel coded 2N-PAM can be decomposed into N parallel binary channels. Thus, the node can assign its own information...
Cyclic delay diversity (CDD) exploits the principle of the orthogonal frequency division multiplexing (OFDM) that transforms the delay spread into the frequency selectivity. In order to investigate the performance of the CDD, OFDM in combination with bit-interleaved coded differential phase shift keying (DPSK) is theoretically analyzed in terms of pairwise error probability (PEP). We show that bit-interleaved...
In this paper, we design a new turbo-based coded cooperation scheme for half-duplex scenario utilizing superposition modulation. The cooperative diversity utilizing superposition modulation which is classified into decode-and-forward protocol has been proposed. We extend this system to coded-cooperation protocol in order to improve the performance. In the proposed system, the transmitting node encodes...
