Underwater Acoustic Sensor Networks (UASNs) have attracted increasing interest in recent years due to their extensive commercial and military applications. However, the harsh underwater channel causes many challenges for the design of reliable underwater data transport protocol. In this paper, we propose an energy efficient data transport protocol based on(More)
Aim at improving the performance and efficiency of AODV protocol in Tactical MANETs which has large scale and fast changing topology, a novel AODV algorithm - LRM-AODV based on local route maintenance is proposed. According to the feature that there always exist many idle nodes, LRM-AODV adopts reverse route search procedure for idle nodes to produce many(More)
Coherent decoys can guide the passive radar seeker (PRS) of anti-radiation missile (ARM) to a point completely outside the extremities of target. The difficulty of the final practicality of coherent jamming is the accurate phase difference control of two coherent decoys at PRS. Model of two coherent decoys jamming ARM is built in this paper, which includes(More)
—Coherent decoys can induce anti-radiation missile (ARM) to the area outside radiant sources compared with the noncoherent decoys technology widely used now, the choke point of final utility of coherent decoy is the accurate control of radiant sources' phase difference. Model of two radiant sources decoying ARM is built in this paper, relationships between(More)
Because of the intrinsic defect of passive radar seeker (PRS) of ARM, it can't distinguish coherent decoys from far distance. Using extended-aperture confronting coherent decoys for ARM is proposed in this paper, and a new 2-dimentional DOA estimation ESPRIT algorithm is presented. This algorithm uses the characteristic of a new special array to construct a(More)
This paper proposes a recursive optimum-term selecting (ROS) approach to pruning the general Volterra series, by which we can achieve a custom-tailored model to characterize nonlinearity of wideband power amplifiers (PAs) with memory effects. The achieved model is more suitable for the individual PA than those static models , such as the MP and GMP models,(More)
This paper presents a suboptimum custom-tailored (SCT) model for power amplifiers (PAs). Based on the pruned Volterra series, the SCT model is developed by using a recursive optimum-term selecting (ROS) algorithm with an offline characterization process. The proposed model sacrifices accuracy in comparison with the custom-tailored (CT) model derived from(More)
In current cooperative communication schemes, to achieve cooperative diversity, synchronization between terminals is usually assumed, which may not be practical. In this paper, shift-orthogonal space-time block codes (SOSTBC) for relay networks without the assumption of synchronization is described. Then based on the set of zero correlation zone (ZCZ)(More)
