In this work, we obtain lower and upper bounds on the maximal transmission rate at a given codeword length n, average probability of error and power constraint P̄ , over a block fading additive white Gaussian noise (AWGN) channel with channel state information (CSI) at the transmitter and the receiver. These bounds characterize deviation of the finite blocklength coding rates from the channel ca...

We consider the uplink reachback problem in sensor networks where the receiver is equipped with multiple antennas and linear multiuser detectors. Three medium access control (MAC) schemes are analyzed: round-robin, maximumthroughput scheduling and slotted ALOHA. We optimize the average number of transmissions per slot and the transmission power for two purposes: maximizing the throughput, or mi...

The aim, and main contribution, of this paper is to propose a fine-tuned fast approximator, based on neural networks, that uses aggregated traction system information as inputs and outputs. This approximator can be used as an investment planning constraint in the optimization. It considers that there is a limit on the intensity of the train traffic, depending on the strength of the power system...

Energy harvesting has attached considerably attention for its wide application in wireless green communications. Equipped with a rechargeable battery, a source node can harvest energy from ambient environments and rely on this free and regenerative energy supply to transmit packets. Due to the uncertainty of available energy from harvesting, however, it could induce intolerably large latency an...

Bluetooth is developed for short range communication. Bluetooth Devices are normally having low power and low cost. This is a wireless communication technology designed to connect phones, laptops and PDAs. The greater availability of portable devices with Bluetooth connectivity imposes wireless connection between enabled devices. On an average the range of Bluetooth devices is about 10 meters. ...

As power consumption being the first order constraint to build microprocessors, they are required to achieve high performance within the strictly limited power budget. For example, capping the peak power consumption is a strongly desired feature in large scale data centers or massive HPC machines. Future many-core processors are expected to host a variety of workloads which have different chara...

AbsThe radio frequency identification (RFID) passive tag is wireless communication device with high energy sustainability, such that it uses the incident (RF) signal to backscatter its information. This paper investigates output load power maximization optimal impedances selection in (BackCom) network. The considered BackCom system comprises a reader broadcasting an unmodulated carrier downlink...

Transmission of information over a MIMO discrete-time flat fading channel with an average power constraint is considered. The scenario in which the transmitter alone has knowledge of the fading levels, as side information, is assumed. This knowledge may be provided in either a causal or a non-causal manner. Upper and lower bounds are derived for each of the two cases. The tools developed are ap...
