Abstract: Let R=F2+uF2+u2F2,the depth of a codeword and the depth distribution of linear codes over ring R are defined,a number of properties of the depth of codewords are studied,and the recursive algorithm for computing the depth of a codeword is given.Based on the linear codes over R and their generator matrices,the linear codes C1,Cu,Cu2 over F2 and their generator matrices are obtained.By using the relationship of C1,Cu,Cu2,the depth distribution and the depth spectrum of linear codes over R are discussed,moreover the depth distribution of a class of linear code over R is showed.

Key words: linear code, generator matrix, depth distribution, depth spectrum
