| Abstract: | The principle of self-encoded spread spectrum communication is introduced. AR-SESS system which employs AR filter technique to obtain the spreading codes from the source sequences is proposed. And the paper analyzes and simulates the performance of Bit-Error-Rate (BER) and the multiple access capability of this system. The analysis and simulation 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 the practical application of the SESS system. |
