presented for two measured VHF channel transfer function time series illustrate the importance of the channel characteristics and choice of system parameters
Furthermore, simulation results based on channel measurements in the tactical VHF band allow for the evaluation of the overall system performance in typical multipath environments
Thus, it is suitable for vehicle directional communications in tactical VHF.
As a result, it is found that anomalous line-of-sight propagations on VHF band might be associated with the earthquakes near the VHF propagation path.
We advocate the implementation of such a system in the lower VHF band due to its favorable channel characteristics and and especially its reduced multipath and frequency offset sensitivity.

In particular, we show that when the main channel is more capable than the eavesdropping channel, channel prefixing is unnecessary; the entire rate-equivocation region can be achieved by rate splitting alone.
Meanwhile, the radiation patterns are stable in the desired band, which indicates that the proposed antenna is suitable for broadband application in VHF band communications.
The author argues that a channel effectiveness is largely predicated on both the channel system and the channel partner effectiveness.
Therefore, to acquire the channel knowledge, channel state information is required at the base station and estimating the channel parameters plays an important role.

What are the different channels through which messages can be communicated?4 answersThere are several channels through which messages can be communicated. One approach is to utilize a control channel to communicate messages between nodes, which can then indicate a particular data channel for transferring data. Another option is to use message-passing services, or channels, which allow users at different locations to transmit messages to each other. Additionally, a message communication channel can be established by configuring messages to indicate a particular image for output in conjunction with messages from the sender. In the context of interference and broadcast channels, independent confidential messages can be sent to two receivers with perfect secrecy. Finally, different communication channels, such as Instant Messenger, email, text messages, and mobile phones, facilitate different levels of connectedness and are chosen based on the desired degree of connection.
What are the common communication channels or methods for project communications?3 answersCommunication channels commonly used for project communications include mailing lists, forums, issue trackers, chat systems, and email addresses. In open-source projects on GitHub, the most common channels are GitHub Issues, email addresses, and the chat system Gitter. Mailing lists have a lower market share compared to modern chat systems. Additionally, there are various types of communication channels, such as chat, that can be provided in multiple channels within a project. Maintainers of projects are aware of the different properties of channels and help developers decide which channel to use for different purposes. However, the reasons for choosing one channel over another are not always explicitly stated. It is important for maintainers to carefully select and clearly communicate which channels should be used in which cases to avoid overwhelming developers and fragmenting information.
What are the main channels used in mobile communication?4 answersThe main channels used in mobile communication include broadcast channels, control channels, and user data channels. These channels are essential for transmitting and receiving data in a mobile communication system. The broadcast channel includes a system frame number (SFN) and provides important information to the mobile communication apparatus. The control channel includes a process number (Proc) and new data identification, which are used for error detection and reporting. The user data channel includes a sequence number and is responsible for transmitting user data. These channels play a crucial role in ensuring efficient and reliable communication between mobile devices and the network.
