Fast ESPRIT Algorithm Without Eigengdcomposition
Luo Lang · Journal of Hunan Institute of Engineering · 2006
ESPRIT is a super-resolution parameter estimation technique for determining directions of arrival(DOA) of a set of narrowband signals impinging on an array of sensors.Because of its excellent performance in validity and stability,ESPRIT is widely researched and becomes one of the main super-resolution methods. Unfortunately,its computational burden makes it unsuitable for real time processing of signals with time-varying DOA because the previous ESPRIT is based on the eigendecomposition or singular value decomposition.In this paper,we propose a new implementation of ESPRIT without eigendecomposition that has potential for real time processing.
