It is known that a good performance can be obtained when the DOAs are estimated directly from the signal direction vectors.

由信号方向向量直接估计到达波方向(DOA)可以获得优良的估计性能。

Based on the combination of the ESPRIT with the signal subspace technique, a complete expression for the signal direction vectors is derived in this paper.

本文将ESPRIT技术与信号子空间技术相结合，给出了信号方向向量的完整表达式。

Most other tracing studies at present focus only on one signal, in one direction, at one location.

目前大多数其他跟踪研究，只集中于对一个地点的一个方向上的一个信号的研究。

The move could signal a new direction for staffing: JPMorgan already shed about 1, 200 jobs in 2012, after adding jobs in 2011 and 2010.

They would also signal a change of direction: previous tax cuts have been narrow and temporary.

While this step does not constitute US recognition of a Palestinian state in the absence of a peace treaty between the Palestinians and Israel, it certainly sends a clear signal that this is the direction the US is heading.
