An Improved DOA Estimation Approach Using Coarray Interpolation and Matrix Denoising
Co-prime arrays can estimate the directions of arrival (DOAs) of O ( M N ) sources with O ( M + N ) sensors, and are convenient to analyze due to their closed-form expression for the locations of virtual lags. However, the number of degrees of freedom is limited due to the existence of holes in difference coarrays if subspace-based algorithms such as the spatial smoothing multiple signal classi...
متن کاملWideband DOA Estimation through Projection Matrix Interpolation
This paper presents a method to reduce the complexity of the deterministic maximum likelihood (DML) estimator in the wideband direction-of-arrival (WDOA) problem, which is based on interpolating the array projection matrix in the temporal frequency variable. It is shown that an accurate interpolator like Chebyshev’s is able to produce DML cost functions comprising just a few narrowband-like sum...
متن کاملFast DOA estimation using wavelet denoising on MIMO fading channel
This paper presents a tool for the analysis, and simulation of direction-of-arrival (DOA) estimation in wireless mobile communication systems over the fading channel. It reviews two methods of Direction of arrival (DOA) estimation algorithm. The standard Multiple Signal Classification (MUSIC) can be obtained from the subspace based methods. In improved MUSIC procedure called Cyclic MUSIC, it ca...
متن کاملA Direct Coarray Interpolation Approach for Direction Finding
Sparse arrays have gained considerable attention in recent years because they can resolve more sources than the number of sensors. The coprime array can resolve O ( M N ) sources with only O ( M + N ) sensors, and is a popular sparse array structure due to its closed-form expressions for array configuration and the reduction of the mutual coupling effect. However, because of the existence of ho...
متن کاملAn Improved DOA Estimation Algorithm Based on Wavelet Operator
In array signal processing, direction of arrival (DOA) estimation has typically play a key role. Its task is to find the directions impinging on an array antenna to increase the performance of the received signal. How to let DOA estimation methods are applicable to most environments, has become the key of technique implementation. The previous traditional algorithms can get superior performance...
