Underwater Communication Channels,e physical properties of the ocean determine the relative advantages or disadvantages of underwater communication systems. To this end, the theoretical study of information propagation through noisy channels produces reliable quantitative measures of the operational performance of communication deviINTER 发表于 2025-3-22 01:08:48
Underwater Optical Communications: Technology,omings to the use of this underwater communication channel. But perhaps more restrictive, these systems are characterized by a extremely small data bandwidth, about 300 bits per second for VLF and a few bits per minute for ELF.健壮 发表于 2025-3-22 06:58:38
Underwater Optical Communications: System Performance,imit our discussion to the use of the APD and BQP sensors described in Chapter 5. For simplicity, in what follows we will ignore atmospheric effects and concentrate our analysis on the underwater channel.

Conclusions, effect on the communication systems that can be deployed by a naval fleet. In particular, we described why underwater vehicles are required to communicate while operating at depths in excess of 60-100 m. In general, the most desirable mechanism for underwater vehicle-to-satellite communications wou规章 发表于 2025-3-22 15:24:09

Underwater Communication Channels,ces. In this chapter we will rely on an information-theoretical analysis to determine the specific advantages and disadvantages of the most widely used underwater communication channels: fiber optics, acoustic, radio-frequency (RF), and optical.BRIDE 发表于 2025-3-23 07:25:44
Underwater Optical Communications: System Performance,nd concentrate our analysis on the underwater channel. That is, our interest is the quality of the transmission on the water column above an underwater vehicle traveling below the mixed layer. However, a detailed link budget of the system should consider the non-negligible effects created by the atmospheric column and the air-water interface.
