Talk:MUSIC (algorithm)

Issue: Verbatim from article
The description of the MUSIC algorithm in this article is a sentence from the first paragraph then the entire second paragraph of the section "Introduction" from Roy, R. and Kailath, T.'s "ESPRIT—Estimation of Signal Parameters Via Rotational Invariance Technique."
 * Does this mean it violates copyright?
 * Also, the wording of the huge paragraph sounds out of date: It refers to events that were new in 1998 as though they are still current. Jmacwiki (talk) 03:13, 24 May 2018 (UTC)

What are the disadvantages of this algorithm? Will the cost of related systems be high?
