FPGA-based real-time implementation for direction-of-arrival estimation
The Journal of Engineering, 2017 Direction-of-arrival (DOA) estimation of radio signals is of utmost importance in many commercial and military applications. In this study, the authors propose an efficient field-programmable gate array (FPGA) architecture for implementing a recently ...

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 ...

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

Multispectrally Constrained Waveform Design for MIMO Radar Direction Finding
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This paper focuses on the design of transmit waveforms for multiple‐input‐multiple‐output (MIMO) radar systems in a spectrally crowded environment. The purpose is to improve the angle estimation performance of MIMO radar by minimising the asymptotic estimation bound of multiple signal classification (MUSIC) algorithm.

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.

OMP-type Algorithm with Structured Sparsity Patterns for Multipath Radar Signals [PDF]
, 2011 A transmitted, unknown radar signal is observed at the receiver through more than one path in additive noise. The aim is to recover the waveform of the intercepted signal and to simultaneously estimate the direction of arrival (DOA).
