摘要： Secure channel training to enhance the confidentiality level of a power domain non-orthogonal multiple access (NOMA) communication system when impaired by eavesdropping attacks coming from inside and outside of the network. In a first scenario, a cooperative jammer available in the system defines an external source of entropy that is independent of the channel variation rate. While the jammer provides secrecy inside the network, the proposed invention is configured to secure the network from outside, encoding the system information, which is exchanged during the training phase, using only the channel state. In a second scenario, the cooperative jammer is not available; with the secrecy inside and outside of the network ensured through a different parameterization. That parameterization is done in a way that the required system information is encoded using not only the channels, but also a random phase defined in the data communication phase.

摘要： A computer server receives sensor data via a cellular wireless network from each of a plurality of automobiles in a geographical area. In each automobile of the plurality of automobiles the sensor data is received from sensors located in the respective automobile. The sensor data of the respective automobile may include a time stamp of the sensor data and at least one parameter of an external environment of the respective automobile. The computer server may further determine an external environmental parameter of the geographical area based on the sensor data received from the plurality of automobiles in the geographical area via the cellular wireless network. The external environmental parameter relates to the external environment of the plurality of automobiles in the geographical area. The computer server may transmit the external environmental parameter to multiple automobiles of the plurality of automobiles.

摘要： A random phase modulation method depending on a communication distance is provided. In the method, time synchronization is carried out by means of a transmitter and a receiver, a local random signal is generated, and an original signal to be sent is pre-coded according to a transmission delay and the generated local random signal, such that random phase modulation depending on a communication distance is realized, potential security brought about by positions of the transmitter and the receiver is fully utilized, a receiver at an expected distance position can receive a signal with a correct phase, and a receiver at another distance position receives a signal with a scrambled phase, thereby improving the secure communication capability of a wireless communication system in terms of the dimension of space.

摘要： A system and method determine a clock drift and a clock variance of each node in plural nodes of a time-sensitive Ethernet network. An accumulated clock offset along a time-sensitive network path in the time-sensitive network is determined based on the clock drifts and the clock variances. A guard band having a dynamic size is determined based on the accumulated clock offset. The times at which Ethernet frames are communicated through the nodes are restricted by communicating the guard band with the dynamic size to one or more of the nodes.

摘要： An electronic device may be configurable to operate in a scrambling mode and a non-scrambling mode while processing chat audio and microphone audio for a first player participating in an online multiplayer game. While operating in the non-scrambling mode, the electronic device may be configured to transmit the microphone audio without scrambling the microphone audio. While operating in the scrambling mode, the electronic device may be configured to scramble the microphone audio and transmit the scrambled microphone audio. The electronic device may be operable to select a scrambling key used to scramble the microphone audio based on a signal received by the electronic device that indicates a role of the player in the online multiplayer game. The role of the player may correspond to which of two or more opposing teams the first player is a member of in the online multiplayer game.

摘要： A communication apparatus includes a reference signal generating section, a transmitting section, a propagation estimating section, a first data acquiring section, and a decoding section. The reference signal generating section generates a first reference signal to enable a communicating party to estimate a propagation environment. The transmitting section transmits the first reference signal. The propagation estimating section estimates a first propagation estimation value of the propagation environment using a second reference signal transmitted from the communicating party. The first data acquiring section generates first data using the first propagation estimation value. The decoding section decodes a transmission signal encoded using a second propagation estimation value that is estimated by the communicating party using the first reference signal, to obtain second data using the first data.
