Dear all: This question includes WSS, random processing, and frequency estimation. may I have any idea from you? Thanx.. :) Question: Consider the WSS process x[n]=A cos(Ωn+ψ) where ψis uniformly distributed between 0 and 2π and the other parameters are deterministic. (a) Is there an advantage to use Bartlett method over the periodogram?explain. (b) Is there an advantage to using Modified periodogram over the periodogram?explain. (c) Does your answer to part (a) change if you are to estimate the PSD of y[n]=x[n]+w[n], where x[n] is as above and w[n] is a zero-mean white noise process? explain. -- = [Origin] 中興電機 拿鐵屋 bbs.ee.nchu.edu.tw = [Author] huhu post from cpe-72-227-52-99.stny.res.rr.com
