NON-ASYMPTOTIC PERFORMANCE ANALYSIS OF DOA ESTIMATION BASED ON REAL-VALUED ROOT-MUSIC

This paper presents a systematic theoretical performance analysis of the Real-Valued root-MUSIC (RV-root-MUSIC) algorithm under non-asymptotic conditions. A well-known limitation of RV-root-MUSIC is the estimation ambiguity caused by mirror roots, which are typically suppressed using conventional be…
