In this paper, an Administrable Shortcut transmission (AST) scheme in two-hop relay networks which enables two Subscriber Stations (SSs) within the same Relay Station (RS) communicate directly via RS's forwarding has been investigated. The scenario of AST scheme in two-hop relay networks and a path selection algorithm based on the minimum slot number with AST scheme are put forward. The simulation results show that the system performance is improved significantly with the increase of the probability of AST scheme taken into account. Therefore, AST scheme could be a potential technology for improving system performance in next generation wireless networks.

Primary synchronization detection is used as the first step for cell searching in the FDD-LTE system, which completes the functions of timing synchronization, cell ID identifying and frequency offset estimation and so on. Fast, efficient and accurate primary synchronization detection algorithms are the preconditions to let users access to the proper cell quickly. Introducing several classic timing synchronization algorithms, the paper mainly focused on the timing synchronization algorithm, i. e., the primary synchronization detection algorithm, for orthogonal frequency division modulation (OFDM) in the FDD-LTE system. Meanwhile, the improved method based on the primary synchronization detection algorithm was proposed to achieve lower *** theoretical analysis and simulation results indicate that the proposed algorithm is characterized by low computation complexity and fast detection convergence.

The erroneous sensor reading due to the harsh environmental conditions usually leads to Byzantine faults. Therefore, faulttolerance becomes a crucial problem in target detection for wireless sensor networks. In this paper, we propose hierarchical value fusion scheme and it is validated that, the algorithm can enable energy-efficient target detection with some increase in the processing time delay compared with that of the value fusion algorithm, thus offering an attractive alternative scheme for the time-delay insensitive target detection application.
