Simplex transmission mode is the most basic form of communication in which data flows in one direction only. The term 'simplex' is derived from Latin, meaning 'simple' or 'single', reflecting the one-way nature of this mode. In this mode, one device is designated as the transmitter ...
Increasingly, mobile devices have multiple radios to simultaneously access different parts of the spectrum, e.g., cellular and ISM bands. The ability of simultaneous access to multiple parts of the spectrum provides an opportunity to use multiple bands in new and unique ways. A common method is ...
Time-division multiplexing (TDM)combines multiple data streams in a single communication channel. TDM divides the individual streams into small segments that are scheduled for transmission across the channel at different times. Frequency-division duplexing (FDM)combines multiple signals on a single communi...
The input to a PCZ is a frequency domain multiplexed (FDM) signal, and the output is a time domain multiplexed (TDM) signal. The input FDM signal can represent, for example, a dedicated channel for one user or a channel that is shared across multiple users using spreading codes within ...
Of the wide variety of numerical methods used to simulate seismic wave propagation, the staggered-grid finite difference method (FDM) has been widely used in the seismological community. The staggered-grid FDM with second-order accuracy in space and time to simulate seismic waves was first proposed...
A 60 W SWIPT prototype with a full-duplex communication rate of 20 kbps is built to verify the proposed method. Keywords: bidirectional power transmission; crosstalk; FSK; full-duplex information transfer; infor- mation transfer channel gain; SWIPT 1. Introduction Based on convenience and safety,...
The idea of Primary User Emulation Attack (PUEA) is similar to jamming, as it attempts is to create a situation where a user will decide not to use a channel. It is one form of a Denial of Service (DoS) attack. In the case of PUEA, the secondary user (SU) senses that the channel...
