Wireless capsule gastrointestinal endoscopy: direction of arrival estimation based localization survey [PDF]
, 2017 One of the significant challenges in Capsule Endoscopy (CE) is to precisely determine the pathologies location. The localization process is primarily estimated using the received signal strength from sensors in the capsule system through its movement in ...

Low‐Complexity DOA Estimation: Combining VSSLMS With FFT Spectrum Estimation
Electronics Letters, Volume 62, Issue 1, January/December 2026.This letter presents a novel, low‐complexity framework for DOA estimation. The proposed method achieves a significant reduction in computational complexity—from O(ML) to O(M log L)—compared to conventional SSE methods. Crucially, as illustrated in the accompanying figure, the method maintains high estimation accuracy, outperforming standard SSE‐based ...

Improved CPD based DOA estimation of nested array
Dianxin kexue, 2021 In order to avoid searching the peak value in space domain, when estimating nested array’s the direction of direction of arrival(DOA), the canonical polyadic decomposition(CPD) was applied into the nested array, namely using the one time singular value ...

Loop Matching Pursuit Multistation TDOA Estimation Method Based on Noncircular Signal
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.The existing TDOA estimation methods based on orthogonal matching pursuit only consider the scenario of circular signal and are prone to the degradation of estimation performance due to atom misselection under small samples and low signal‐to‐noise ratio.

Adaptive channel selection for DOA estimation in MIMO radar
, 2017 We present adaptive strategies for antenna selection for Direction of Arrival (DoA) estimation of a far-field source using TDM MIMO radar with linear arrays. Our treatment is formulated within a general adaptive sensing framework that uses one-step ahead

Quadratically Constrained Beamforming Robust Against Direction-of-Arrival Mismatch [PDF]
, 2007 It is well known that the performance of the minimum variance distortionless response (MVDR) beamformer is very sensitive to steering vector mismatch. Such mismatches can occur as a result of direction-of-arrival (DOA) errors, local scattering, near-far ...

British Journal of Management, Volume 37, Issue 1, January 2026.Abstract Although the renewed interest in retro‐games has drawn attention to the importance of nostalgia in enhancing their market appeal, the antecedents of nostalgia arousal and its implications for gamers’ behaviour remain underexplored. To address this gap, we follow a discovery‐oriented approach that synthesizes literature and field‐based insights

Performance Improvement for Wideband DOA estimation with White Noise Reduction Based on Uniform Linear Arrays [PDF]
, 2016 A method is proposed for reducing the effect of white noise in wide- band uniform linear arrays via a combination of a judiciously de- signed transformation followed by highpass filters. The reduced noise level leads to a higher signal to noise ratio for
