Talk:Estimation of signal parameters via rotational invariance techniques

Hello, colleagues! What are you thinking about covering of the stuff about Unitary ESPRIT (a.k.a. TLS-ESPRIT) in this article? In one hand, this is widespread method in the communications, which even included in the [https://ch.mathworks.com/help/phased/ug/high-resolution-direction-of-arrival-estimation.html MATLAB ULA toolbox]. In other hand, I'm afraid that the mathematical description can be ambiguous for the Wikipedia article. There are several open-access materials on the Internet about Unitary ESPRIT (scientific articles Haardt, M., Zoltowski, M.D., Mathews, C.P. and Ramos, J., 1998. [http://dsp-book.narod.ru/DSPMW/63.PDF ESPRIT and closed-form 2D angle estimation with planar arrays. In Digital Signal Processing Handbook.] Boca Raton, FL: CRC Press. Ren, S., Ma, X., Yan, S. and Hao, C., 2013. [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3673083/ 2-D unitary ESPRIT-like direction-of-arrival (DOA) estimation for coherent signals with a uniform rectangular array]. Sensors, 13(4), pp.4272-4288., [http://mikkelschmidt.dk/papers/schmidt2003masters.pdf Master Thesis]), and I guess, MATLAB examples can also be found... Maybe, this method should be at least mentioned, I don't know, frankly speaking. — Preceding unsigned comment added by Kirlf (talk • contribs) 08:20, 28 January 2022 (UTC)

What do you think about the current status of the article? How can it be improved?

I started the rework of this article. However, I am not an expert in English language nor an expert on how to write mathematical things on Wikipedia. Some articles give proofs of their claims and some give general ideas. So, it is not clear to me what is judged as textbook style (even after reading about it).
