    The maximum likelihood (ML) estimator demonstrates remarkable performance in direction of arrival (DOA) estimation for the multiple input multiple output (MIMO) sonar. However, this advantage comes with prohibitive computational complexity. In order to solve this problem, an ant colony optimization (ACO) is incorporated into the MIMO ML DOA estimator. Based on the ACO, a novel MIMO ML DOA estimato... View full abstract»

    Multiuser detection can be described as a quadratic optimization problem with binary constraint. Many techniques are available to find approximate solution to this problem. These techniques can be characterized in terms of complexity and detection performance. The “efficient frontier” of known techniques include the decision-feedback, branch-and-bound and probabilistic data associati... View full abstract»

    The track association problem of radar and electronic support measure (ESM) has been considered in the literature for several years. This problem is crucial for radar-to-ESM track fusion and is complicated by the presence of individual systematic errors and measurement errors. In order to improve the track association of radar and ESM sensors, a pseudo-linear filtering algorithm is proposed to est... View full abstract»

  • Nonlinear RCMC method for spaceborne/airborne forward-looking bistatic SAR

    Publication Year: 2012, Page(s):201 - 207
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1397 KB)

    In the spaceborne/airborne forward-looking bistatic synthetic aperture radar (SA-FBSAR), due to the system platforms' remarkable velocity difference and the forward-looking mode, the range cell migration (RCM) not only depends on the target's two-dimensional location, but also varies with the range location non-linearly. And the nonlinearity is not just the slight deviation from the linear part, b... View full abstract»

  • Self-adaptive large neighborhood search algorithm for parallel machine scheduling problems

    Publication Year: 2012, Page(s):208 - 215
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (463 KB)

    A self-adaptive large neighborhood search method for scheduling n jobs on m non-identical parallel machines with multiple time windows is presented. The problems' another feature lies in oversubscription, namely not all jobs can be scheduled within specified scheduling horizons due to the limited machine capacity. The objective is thus to maximize the overall profits of processed jobs while respec... View full abstract»

    Power efficiency and link reliability are of great importance in hierarchical wireless sensor networks (HWSNs), especially at the key level, which consists of sensor nodes located only one hop away from the sink node called OHS. The power and admission control problem in HWSNs is comsidered to improve its power efficiency and link reliability. This problem is modeled as a non-cooperative game in w... View full abstract»

    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (3072 KB)

    Classical network reliability problems assume both networks and components have only binary states, fully working or fully failed states. But many actual networks are multi-state, such as communication networks and transportation networks. The nodes and arcs in the networks may be in intermediate states which are not fully working either fully failed. A simulation approach for computing the two-te... View full abstract»
