how to analyze time series structures?
...model is 5 as suggested by Bayesian information criteria. *All error bands for this paper should generated with 2000 Monto Carlo draws. The corresponding impulse responses should reported in the figures(use one-standard deviation shock in order to see impulses.). and I need these outputs; *plot impluse-response figures and should define level of confidence bonds in the figures for every sub-periods *t values of responses from ISE to DJIA.(for 10 days) Finally, I am not good at R statistics(inexperienced) so I need explanations in detailed also need resources and ready-made codes. How I use MSBVA...

Acoustic echo cancellation
...u please explain what you mean by >align samples from near-end and far-end? And how is that usually >accomplished? You need to know the total delay caused by DAC buffer before speaker, ADC buffer after microphone and acoustic path between speaker and microphone. Simply to say, if you play an impluse signal and its first echo appears after N sample cycles, you can call N as the delay between y (echo in near-end signal) and x (far-end signal). Then you can buffer far-end signal for N-M cycles before sending to AEC. M is a little number (such as 100) in order to avoid filter failure when echo pat...
