Read the textbooks. If the paper is old, then the recent textbooks will present the same material with more easy-to-follow structure and simpler language. If the paper is recent, then the authors either don't know that the material is textbook - which in turn means they don't know what they are talking about - or they assume that the reader already know the textbooks. Either way: Read the textbooks. Rune
From: kk KKsingh on 21 Feb 2010 12:00 Ok! But it will be great if u can refer some book too! And about concept I saw this in the recent 2007 paper and in 1999 paper too and its not wrong any where .....I am coding it wrong But sure thanks for your advice i will go through books if i can approach for irregular sampling some where Rune Allnor <allnor(a)tele.ntnu.no> wrote in message <688e9a23-a71f-4ed1-b97c-67b5b105da07(a)f29g2000yqa.googlegroups.com>... > On 21 Feb, 09:32, "kk KKsingh" <akikumar1...(a)gmail.com> wrote: > > I am just trying to code a algorithm, I read in Paper ! > > Don't read the papers.

We've been doing it for years. So we know, without having to prove it to ourselves or you. And we learnt, not by continually bugging others, but by knuckling down and figuring it out for ourselves, using textbooks. You've posted 30 or so messages this month on this subject. It's time you did some work for yourself instead of continually asking questions and expecting others to do your work for you.

I'll do better than that; I'll mention two: Oppenheim and Schafer: Digital Signal Processing (1975) Papoulis: The Fourier Integral and its Applications (1961) Your local academic library will have a copy of each. One just needs to know that a 'library' is a collection of 'books'. And how to use the books. And what to use them for. Rune |
