| Zusammenfassung: | A hydroacoustic communication system employs spread spectrum to mitigate multipath interference caused by acoustic reflections off underwater surfaces and other large boundaries or acoustic discontinuities. The system is particularly beneficial for mitigating errors due to surface reflections, and for mitigating interference due to unwanted signals having a delay ranging from tens of microseconds to hundreds of milliseconds. |
