Abstract

A high-efficient distance spectrum calculation approach for turbo code is proposed in this paper. It uses periodic characteristic of recursive systematic code in turbo codes to define a fundamental period. The distance spectrum can be calculated with leadfrog method by utilizing the fundamental period look-up table instead of using bit-by-bit basis calculation. The error patterns can be classified into groups of turbo codewords in term of the different fundamental periods. Thus, the computational time of distance spectrum can be reduced dramatically. Simulation results show that the proposed algorithm is applicable to turbo codes with the block length as large as eight thousand bits with a reasonable computational time.
