The aeronautical wireless channel can be modeled as a sparse double-selective channel, which includes a strong line-of-sight (LOS) path and a weak reflected diffuse path Compared with the LOS path's, delay and Doppler shift of the reflected path are more difficult to be estimated, which are time-varying and non-stationary. With equalization using(More)
In order to enable Ultra-Wideband (UWB) spectral mask compatibility and provide simple hardware implementation, novel pulse shaping methods based on orthonormal Hermite functions are proposed to enable the pulses to fulfill given spectral mask. Simulation results show that the proposed method can be used to obtain pulses that fulfill the FCC spectral mask,(More)
In some warning applications, such as aircraft taking-off and landing, ship sailing, and traffic guidance in foggy weather, the high definition (HD) and rapid dehazing of images and videos is increasingly necessary. Existing technologies for the dehazing of videos or images have not completely exploited the parallel computing capacity of modern multi-core(More)
In this paper, an iterative high-resolution DOA algorithm is proposed for DOA estimation for CDMA systems. The algorithm iteratively removes detected signals from the received data and searches the residue spatial spectrum for further signals. It does not require any computationally expensive eigen decomposition or spatial smoothing in coherent multipath(More)
