In a multipath communication scenario, it is often relevant to estimate the directions and relative delays of each multipath signal. We present an effect algorithm for the simultaneous estimation of these parameters by re-iterative super-resolution, beamforming, and MUSIC-like searching techniques. The algorithm first separates and estimates direction of arrival (DOA) of the multipath signals. Linear...
A fully instrumented surface vessel involving underactuated structure was designed. The problem of straight line course tracking of the underactuated surface vessel at a constant forward speed is addressed. The Serret-Frenet frame is used to define the tracking error, therefore the position tracking errors could be stabilized by stabilizing the single distance error. Least Squares Support Vector Machines...
Consider the problem of source number detection in the presence of nonuniform noise, a new method based on the orthogonality of noise subspace and signal subspace is proposed. Estimate the direction of any incident signal, get eigen-decomposition of the covariance matrix and calculate the inner product vector of eigenvector and the steering array vector. Then a sequential hypothesis test is proposed...
The bootstrap is a great technique for assessing the accuracy of parameters estimator in situations where conventional techniques are not valid. In this article, we highlight the motivations for using the bootstrap in array signal processing applications. ESPRIT and bootstrap methods combines are combined into one novel technique to solve the DOA (Direction of Arrival) estimation of sources arriving...
Time-frequency distribution (TFD) method has received a considerable amount of attention in Direction of Arrival (DOA) estimation of multi-senor and time space processing, which lead to improved spatial resolution and source separation performances. According to the characteristic of the different time-frequency distribution of each source, a novel approach of time-frequency DOA estimation is provided...
