This paper introduces an error-correcting coding and interleaving scheme in wireless data transmission system.The scheme uses interleaving to transmit burst errors into random errors

and then corrects the random errors by extended hamming code which usually used to correct random errors.After introducing the coding method of extended hamming code and the theory of improve the ability of anti-interference by using interleaving

we analyze its ability of error correction

then a method to implement the coding i..
