Covert Communication via Dynamic Spectrum Control-Assisted Transmission

To realize secure communication and prevent eaves-droppers from detecting the existence of communication activities, covert communication has attracted substantial research interests. In this paper, we propose a dynamic spectrum control (DSC)-assisted scheme to achieve covert and reliable data transmission. Specifically, by constructing time …

An efficient random access scheme for OFDMA systems with …

Moreover, to further improve the utilization of RACH in an OFDMA system, we propose a novel message transmission scheme in a shared RACH. The message in the proposed scheme can be sent implicitly in the cyclic-shifted preambles which make the transmission much more reliable in a contention based RACH. Meanwhile, …

However ...

Process Control Block in OS

When the jobs moves through the system and makes progress, it changes it's states from HOLD to FINISH. When the job is being processed by the job manager and the process manager, it is always in one of these 5 states: HOLD: When a user submits a job and it accepts the job, the job is put on HOLD and placed in a queue.

5.5: Reservoirs of Infection and Disease Transmission

Vehicle transmission occurs when a substance, such as soil, water, or air, carries an infectious agent to a new host. Healthcare-associated infections (HAI), or nosocomial infections, are acquired in a clinical setting. Transmission is facilitated by medical interventions and the high concentration of susceptible, immunocompromised …

TCP 3-Way Handshake Process

The TCP 3-Way Handshake is a fundamental process used in the Transmission Control Protocol (TCP) to establish a reliable connection between a client and a server before data transmission begins. This …

Principles and Characteristics of Distance Protection

It can also provide both primary and remote back-up functions in a single scheme. It can easily be adapted to create a unit protection scheme when applied with a signalling channel. In this form it is eminently suitable for application with high-speed auto- reclosing, for the protection of critical transmission lines.
