What kind of data do you want to send?If it is 1 to 4 bits of data you can use HT12E Ic connected to your PIC microcontroller and the connecting RF module to the the encoder IC.Use Haltech decoder IC at the receiver side.When you are using haltech encoder and decoder you will et at the receiver what exactly you send.


If the data has more number of bits then you can use usart of PIC microcontroller directly connected to your RF module but now you have a problem,you have to run the usart of microcontroller in a slow speed that matches boud rate of RF module.Also give some formatting to bits.This method is prone to noise but we have once tried it and got 95% success.
