This paper focuses on fusing hyperspectral and multispectral images with an unknown arbitrary point spread function (PSF). Instead of obtaining the fused image based on the estimation of the PSF, a novel model is proposed without intervention of the PSF under Bayesian framework, in which the fused image is decomposed into double subspace-constrained matrix-factorization-based components and residuals...
In view of the long alignment time of ground static base for unmanned aerial vehicle (UAV), an in-flight misalignment attitude estimation method for airborne SINS was presented which was based on GPS observations and a novel model predict filter (MPF). The estimation procedure can be divided into two stage, i.e., coarse estimation stage during the uniform straight-line motion of aircraft, in which...
Match information opinions are presented in this paper. It reveals that the information is relevant not only to the thing's occurring probability but also to the degree of matching the external messages with the internal memory models. The statistical information is fit for the channel coding and the match information is fit for the source coding. Based on the idea of match information, a new memory...
Most conventional techniques for noise adaptation assume a clean initial speech model which is adapted to a specific noise condition using adaptation data accumulated from the condition. In this paper, a different problem is considered, i.e. adapting a noisy speech model to a specific noise condition. For example, the initial noisy model may be a multi-condition model which is used to provide more...
This paper presents a performance comparison of impulse radio ultra wideband (IR-UWB) and multi-band orthogonal frequency division multiplexing (MB-OFDM) for multi-user wireless communication systems. Focusing on the analysis of system performance affected by multi-user interference (MUI) over general additive white Gaussion noise (AWGN) channel, we run a complete system simulation for direct sequence...
To improve the positioning precision of ship in ocean perturbing environment, a decoupling-fusing positioning algorithm (DFPA) is proposed based on velocity-direction constraint (VDC). Firstly, the strong tracking filter (STF) is combined with the VDC by utilizing Lagrange multipliers method to enhance the space relativity of the ship positioning. Then, to decrease the complexity of STF-VDC technology...
