| Abstract: | Based on the principle of Self-encoded spread spectrum communication,AR-SESS system which employs AR filter technique to obtain the spreading codes from the source sequences is introduced.The performance of Bit-Error-Rate(BER) and the multiple access capability of this system are analyzed and simulated.The analysis and simulation results show that AR-SESS improves the BER performance of the conventional SESS system and enhance the performance of the multiple accesses.It provides a good choice for practical application of the SESS system. |

| Keywords: | self-encoded spread spectrum AR model correlation BER performance of multiple accesses |
