Frampton and Martinez meet at a purpose-built stadium for the IBF super-bantamweight title on Saturday.
In February 2013, the two clashed with Frampton taking the European title off Martinez and becoming the first boxer to knock him out.
Martinez said he was out for revenge and to retain his world title.
He told UTV: "It will be the fight of my life."
Construction of a 16,000 seat-temporary open-air stadium is in the advance stages at the former birth place of the Titanic and Martinez said he was looking forward to fighting in the Belfast air.
He added: "In Spain it is always warm and I like the weather here.
"Belfast has been very welcoming, everyone knows who I am and they are always very nice.
"I'm feeling good - like a champion. Training camp has been good and I can't wait for the fight."
