but, what i am looking for is not a remote control unit...
i am in a need of circuit which can recieve infrared signals and decode them in a computer for me...so that i can use them in another pic base remote control.
in other meaning, i need to copy the codes in another remote control.
Seems you are still habituated to spoon-feeding. Before asking for any schematic please try to make use of fantastic search engine that we have i.e. "GOOGLE". It can search just any thing you want and that too free with just a click of a button.
And if someone suggests you to search in google that means he is sure that there is something lying there what you are looking for. So instead of makig conditions like you did in your post post :"(please no searching on Google suggesions" in https://www.electro-tech-online.com/threads/rf-jamming.1515/ why don't you just try and see whether people here suggested you is correct or not?
