Partial CSI Designs for Distributed Space-Time Coding in Wireless Relay Networks
We study the impact of channel state information at transmitter (CSIT) in a wireless relay network in which M relays cooperate via distributed space-time coding (DSTC) together with an amplify-and-forward protocol. Under individual power constraints at relays, we aim at finding the optimal amplifier powers such that pairwise error probability conditioned on CSIT is minimized. With perfect CSIT ...
متن کاملRelay Selection Based Space-Time Coding for Two-Way Wireless Relay Networks Using Digital Network Coding
In this paper, we propose a novel decode-and-forward dual-relay selection technique based on Alamouti space time coding for twoway wireless relay networks (TWRNs). The twoand the threephase TWRN protocol are used in the first and second version of the proposed technique, respectively, to exchange the information symbols of the communicating terminals. In order not to waste any power for transmi...
متن کاملNon-coherent distributed space-time coding techniques for two-way wireless relay networks
To overcome the overhead involved with channel estimation, several non-coherent distributed space–time coding (DSTC) strategies for two-way wireless relay networks (TWRNs) using the amplify-and-forward and the decode-and-forward protocol have been recently proposed that do not require channel state information (CSI) at any node to decode the information symbols. In this paper, novel differentia...
متن کاملCensored Distributed Space-Time Coding for Wireless Sensor Networks
We consider the application of distributed space-time coding in wireless sensor networks (WSNs). In particular, sensors use a common noncoherent distributed space-time block code (DSTBC) to forward their local decisions to the fusion center (FC) which makes the final decision. We show that the performance of distributed space-time coding is negatively affected by erroneous sensor decisions caus...
متن کاملRateless Coding over Wireless Relay Networks Using Amplify/Decode and Forward Relays
In this paper two different rateless transmissionschemes are developed. In the proposed scheme, relay node candecode and forward the message to the destination if they areable to decode it, or amplify and forward the message to thedestination. Based on the analysis and simulation resultsprovided in this paper, the proposed method has bettertransmission time than the scheme which only the relay ...
