Wireless signal processing methods and apparatuses including directions of arrival estimation

摘要

A DOA estimation unit is provided with at least one of two DOA estimation techniques to determine the DOA of signals wireless transmitted. A first technique includes determination of the DOA based at least in part on a relationship between a received signal vector and a number of signal directional vectors. The second technique includes determination of the DOAs of the L multipaths of a signal by searching in a direction range centered on a determined DOA of the signal.
