[Eeglablist] Signal Decomposition

[Santanu Das]

HI:
  I am Santanu Das and a graduate student in ASU. Presently I am trying to
decompose an overlapping signal to it's components.
Assume the model
x(t) = sum_{i=1 to L} A_i *sin( omega t - theta_i)
y(t)= x(t- t_1) + x(t- t_2) + x(t- t_3)

So y(t) is the sum of the time shifted overlapping signals. The time shift
is generally in micro range. In my case, y(t) is known and would like to
extract the  time shifted components of x(t), which means in this case those
3 components.

It would be a great help, if anyone of you could suggest me  some of the
existing methods or some materials.
Thanks,
Regards,
Santanu
