Defamation suite

I was falsely implicated u/s 376 after refusing to marry an arrogant girl. Sessions court aquitted me on June3, 2017. I am posted outside my hometown and I could hardly visit my home once in a year. Recently after a lapse of almost 19 months from my acquital I got a notice for condonation of delay appeal from High court to be heard next month. Now this has prompted me to consider defamation suit. Can I file a defamation suit now and how? please help
