This paper investigates general Z-hop cascaded undirected wireless relay network, where the source, the relays, and the destination form an undirected chain, and each node receives radio waves from its two neighboring upstream and downstream nodes in the chain. We focus on the effect of time-division duplex and hidden-terminal constraints from two aspects: 1) finding all feasible network states (FNS)...
Consider K-hop cascaded directed relay networks with time-division duplex (TDD), where the source, the relays, and the destination form a directed chain, and each node only receives the transmissions from its upstream node in the chain. We quantitatively investigate the effect of TDD constraint, which obviously prohibits the use of some network states and reduces the whole transmission rate. Firstly...
It is very important to target detecting hardware and algorithm design in the field of target tracking field. A kind of detection algorithm using SVM (support vector machine) and AdaBoost which selects representative Harr characters is proposed. SVM uses selected Harr wavelet characters as input data in training and classifying procedure. In order to accelerate SVM classify and detect speed, the cascade...
