How do i receive binary data without clock signal

I have made a IR transmitter similar to the circuit above using a shift register.
But how do i make a receiver? 
I tried to make one with a shift register with the same clock frequency but the output is messed up so how can i make a receiver. 

I think i can use a begin and end.
Like:  1010-data-0101 
but how do a detect that without a clock

you could transmit a carrier signal for the receiver to sync with

faceblast, i taught on that but a ir receiver only outputs 0/1

How "messed up" is the output of your receiver ? You don't know when it begins/end ? You can use an edge dectector for your pattern : http://everycircuit.com/circuit/5827208097562624

If i send 00101100 it will output 1011 so that's not an option

Use begin and end pattern PLUS an edge detector and a counter, to stop reception (after x bits)
