I have  data in the following form

xi  , Fi  (xi is real but Fi is complex)

i want to determine a fit by using function

F(x, a , b,c, d)=    a Exp(- x^2/b) + c Sin( d x)

a, b, c and d are complex numbers to be determined so as to accurately
represent the data.

How to do this problem?

In principle, FindFit should be able to solve your problem
