the sensitivities of the non-zero bits in the codewords with low weights in Turbo codes to the interruptions are discussed and the result is that the lower weight the higher sensitivity.Theoretical analysis shows that through the protections on such key-bits that have high sensitivities
the minimal weight of the codes can be improved apparently.The simulations also give out the supported results:The BER has been highly improved for code rate both 1/3 and 1/2.
