| () |
| Abstract: |
| A communication method combined M_ary spread spectrum with error correcting code is studied. The application of M_ary spread spectrum makes it easy to acquire high transmission rate. On the other hand, the application of error correcting code enhances the reliability of the communication system. The problem of availability and reliability is solved by combining the two kinds of technology. Simulation results indicate the system has good performance. |
