PIC16F wireless transmit 433Mhz to arduino UNO

hihi....im trying to send a character 'a' from PIC to arduino UNO then based on that light a LED in arduino port.
i will use cheap wireless 433Mhz module transmitter and receiver.

transmitter = Cytron.io - Simplifying Digital Making
receiverhttp://www.cytron.com.my/viewProduct.php?pcode=RF-RX-433

So question is, what is the best way to communicate between PIC and arduino UNO.? anyone interface these two before wirelessly?

If the PIC can support SPI, then Id use a better radio like

otherwise , you will need some preprocessing in the PIC and likewise in the Arduino.
If you can compile Virtualwire for the PIC and also use it in the Arduino, then this will work OK.
