Abstract :
The definition and matrix description of linear cyclic code is introduced in this paper first. Then the distribution of code weight is analyzed. The distance of code weight distribution is defined according to distance of vectors. The theoretic probability of code weight of random sequence is ratiocinated. The method to estimate code weight distribution of actual sequence is established and the code length and start are estimated by the distance between the code weight distribution. The capability of abiding error code of this method is analyzed. The results of simulating experiment to different length code show that this method can estimate code length and start effectively when BER is 10−2.
