before being able to decode a signal, you need to know how the signal is made.
for example, is it an OOK signal?
did you manage to record it and graph it?
THEN you can try to write some code to decode it.
It also depends on the hardware you are using to receive the signal.
I tried with a chinese cheap receiver (something like 1€ on ebay) and could get an amazing range of.. 5cm
so, look deeper at the signal, than come back
