The full-duplex relayed transmission is an expansion of relay technique. In this paper, we investigate an optimal power allocation strategy for the dual-hop full-duplex decode-and-forward (DF) relay system with joint constraint of individual and global power. We prove that the optimal allocation solution is located on the three boundary conditions of the constraint domain. The golden section search...
The Distributed Iterative Localization algorithm (DILOC) is an attractive algorithm for wireless sensor network (WSN), which is used to locate sensors (with unknown locations) in m dimensional space. DILOC algorithm needs a minimal number of m +1 anchors (with known their exact locations). However, the convex hull test requires that sensors must be inside of the convex hull, so it will require relatively...
Applications for future broadband wireless network should work effectively under highly dynamic wireless channel environment, where strong frequency-selective and time-selective fading and severe multi-path channels will exist. Though some advantage techniques, such as 2-dimensional (2D) block spread, frequency domain equalization (FDE) and antenna diversity techniques, can be applied to the code...
Multi-access interference (MAI) free uplink transmission can be achieved by 2-dimensional (2D) block spread code division multi access (CDMA), and low-complexity single-user frequency-domain equalization (FDE) is performed at base station to obtain the frequency diversity gain. Cyclic delay transmit diversity (CDTD) can further improve the transmission performance by obtaining a larger frequency diversity...
