wireless mouse design.....

Hello everyone,

I want to design a wireless mouse.
I have gone through the pin description of the mouse....ps/2

Vcc, GND, DATA, CLK.....

I dont have a proper knowledge on the communication side.
If the data transfer is based on single pin.... i can handle with IR technique...
But there are two signals [data and clock] to be transfered.

If anybody helps in designing this based on IR technique or RF technique....

1. How can i multiplex the two signals into one
2. Any basic circuit of RF transmitter / receiver

help me by giving a small idea......I'll start debugging.........

thankyou
