With every passing day, the demand for data traffic is increasing, and this urges research community not only to look an alternating spectrum communication but also radio frequency planners use existi... | Find, read cite all you need on Tech Science Press

In harmonic radar (HR), the radio frequency transmitter illuminates a nonlinear target (the tag), causing return signal to consist of harmonics at multiples transmitted carrier frequency. Of them, second is usually strongest and one which receiver tuned. This difference distinguishes tag reflection from environmental clutter, remains uplink (transmitter tag) However, passive nature HR tags seve...

While semantic communications have shown the potential in case of single-modal single-users, its applications to multi-user scenario remain limited. In this paper, we investigate deep learning (DL) based communication systems for transmitting data and multimodal data, respectively. We adopt three intelligent tasks, including, image retrieval, machine translation, visual question answering (VQA)...

Electrical activity has numerous roles in early neuronal development. Calcium transients generated at low frequencies regulate neural induction and neuronal proliferation, migration and differentiation. Recent work demonstrates that these signals participate in specification of the transmitters expressed in different classes of neurons. Matching of postsynaptic receptor expression with the nove...

We extend Shannon’s result on the capacity of channels with state information to multiple user channels. More specifically, we characterize the capacity (region) of degraded broadcast channels and physically degraded relay channels where the channel state information is causally available at the transmitters. We also obtain inner and outer bounds on the capacity region for multiple access chann...

Transmitter switching can provide resiliency and robustness to a communication system with multiple energy harvesting transmitters. However, excessive transmitter switching will bring heavy control overhead. In this paper, a geometric projection-based transmitter switching policy is proposed for a communication system with multiple energy harvesting transmitters and one receiver, which can redu...

The frequency assignment problem has been started from the discovery that transmitters, received the same or closely related frequencies, had interferences with one another. Nearly three decade back this problem has been modelled as a graph labelling problem. This labelling has several variations depending upon the type of assignment of frequency to transmitters. Here we shall discuss about som...
