Answer 1

The Systems Identification Toolbox may have what you need.

If you need or want to do it by hand, however (homework?), I would suggest outlining the steps of what needs to be done (break up the problem in parts, starting from the definition of MA models) and asking a more detailed question when you get stuck.
