In this paper, an optimal power allocation scheme for a simple lossy-forwarding relaying system is provided. Here, we extend our previous work of optimal power allocation of Slepian-Wolf relay system with constant source-relay error probability, to such that block Rayleigh fading is assumed for all transmission channel and lossy transmission is assumed in source-relay channel. Since data sequences...
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 after decoding in the information part or not. The results apply to practical fading scenarios where all the links between the nodes suffer from independent...
Cloud-processing techniques in wireless network are emerging in recent years. Due to the resource energy restriction, power optimization schemes are demanded for designing future transmission strategies. However, it is not realistic to consider the techniques of the whole cloud network having massive amount of nodes. Instead, it is quite reasonable that we first decompose the whole network topology...
In this paper, the outage probability of a Slepian-Wolf transmission system is analysed theoretically. We consider two correlated binary information sequences where bit-flipping model is adopted, where the the information bits of the second source are the flipped version of the information bits of the first one, with a probability Pf. Here, we extend our previous work of the correlated sources transmission...
In this paper, we derive the theoretical outage probability of a transmission system in the presence of source and channel correlations in the block Rayleigh fading channels, based on the Slepian-Wolf theorem. Two transmitters and one common receiver are assumed, where the correlation knowledge between the two source information streams can be expressed as a bit-flipping model. The information bits...
With the expansion of the railway industry and the upgrade of railway speed, the reliability and efficiency of wireless communication systems in high speed railway attract the public attention. The high speed brings about more severe Doppler Effect, the postponement of handover triggering location and more frequent handover. Therefore the influence caused by the high speed decreases the reliability...
