| Abstract: |
| The basic principle and decoder structures of turbo codes are discussed in this paper.A new coding scheme based on the association of a turbo code with a bandwidth efficient modulation is also introduced.Finally,the coding schemes are compared with trellis coded modulation schemes. |
