A new code-division multiple access protocol for underwater acoustic network

The paper proposes a new multiple access protocol for underwater acoustic network, which uses a kind of special-designed combined synchronization header to identify different users and process user´s data. By using the CDMA technology, the combining design of different synchronization header and parallel processing of the received collided packet data, the scheme can not only improve the throughput of the network, but also solve the collision problem. Therefore, the performance of the network is greatly improved.
