Sentence examples for duplex device from inspiring English sources

Colour-coded duplex sonography was performed using an Esaote Mylab duplex device with a curved 2 5 MHz transducer following a standardized protocol [ 24].

In the considered MIMO full-duplex device, all of these are obviously known by the digital canceller.

The relay is considered to be a half-duplex device, meaning that it cannot send and receive information simultaneously.

When modeling the phase noise, a common local oscillator for all the transmitters and receivers is assumed, which is a feasible assumption for an inband full-duplex device.

In this section, we build a complete SI channel model for a MIMO full-duplex device, including the effects of transmitter impairments (PA nonlinearity, IQ imbalance, and transmitter crosstalk), the linear MIMO SI channel, and RF cancellation.

Fig. 1 A relay channel consisting of half-duplex devices.

In order to simplify the analysis, we consider orthogonal half-duplex devices that transmit in separate timeslots.

Our model for communication with half-duplex devices in an overlay cognitive radio environment is illustrated in Figure1 and consists of two phases.

aIn contrast to full-duplex devices, half-duplex nodes cannot transmit and receive simultaneously in the same frequency band, which means that they require orthogonal resources (time, frequency) for transmission and reception.

Because of the coarse quantization, the proposed protocol has a low complexity at the relay and can be used with half-duplex devices, making it very suitable for low-complexity applications like sensor networks.

A relaying scheme suitable for half-duplex devices is the quantize-and-forward (QF) protocol, in which the information received from the source is quantized at the relay before being forwarded to the destination.
