Error correction coding

Hello folks,

I have one question regarding secure wireless transmission.

I am using 433 MHz RF communication for one of my project. I want to know how can i use error correction code for successful transmission of my data from Computer to Atmega8 (uC).

I am using Matlab for data transmission. I can encode the data using the in build encoding function such as hamming, crc etc...
But how can i decode it at the microcontroller end?

Thanx in adv...
