rf transmission using ht12e to arduino

i want to use 5 transmitter and 1 receiver, transmitters are using ht12e and receiver is connected to arduino microcontroller. i want to send data like(from transmitter 1 data is "a", from transmitter 2 data is "b" and so on) and i want that receiver which is connected to arduino is receive data correctly. (transmitter is not connected to microcontroller) how to send data?

Your question makes no sense. A Ht12e is a data encoder which is primarily designed to encode a 4 bit nibble into a serial data stream. They arnt designed for sending letters such as a,b,c,d etc. What exactly are you trying to do?
