DOA Estimation Using Time-Frequency Conversion Pre-Processing Method
By
Progress In Electromagnetics Research C, Vol. 24, 13-24, 2011
Abstract
In many cases, the study of DOA estimation techniques is developed based on ideal condition of signal sources and array sensor antennas. But, there are much more errors as a result of signal shadow effects from noise contribution and interference of installation environment in real system. In this paper, the DOA estimation algorithm using the de-noising pre-processing based on time-frequency conversion analysis was proposed, and the performance was analyzed. This is focused on the improvement of DOA estimation at a lower SNR and interference environment.
