Although a number of asynchronous physical-layer network coding (PNC) schemes have been proposed, synchronous PNC may still be preferred for its simplicity. In this paper we propose a new symbol-level synchronization scheme which reduces the misalignment to less than one hardware clock cycle period. In addition, we prototype the proposed scheme on the Universal Software Radio Peripheral (USRP) platform...
In this paper, we consider a sequential approach for decentralized detection problem in wireless sensor networks, and propose a new scheme for data fusion in the case of spatially and temporally identically and independently distributed observations. In addition, we investigate the performances of the proposed scheme in terms of average number of observations and total energy consumption, and further...
Network coding is a technology which has the potential to increase network throughput beyond existing standards based on routing. Despite the fact, that the theoretical understanding is mature, there have been only a few papers on implementation of network coding and demonstration of a working testbed. This paper presents the implementation of a two-way relay network with digital network coding. Unlike...
The decentralized detection problem in wireless sensor network with sequential structure is considered. We propose a new empirical data fusion scheme. This scheme is investigated with assumption of spatially and temporally identically and independently distributed observations and individual energy consumption constraint. The influence of multiple access channel noises is studied. The detection performance...
