Abstract: The location and morphology of an electrostatically manipulated flame can be controlled through the action of an electrostatic field on the flame, virtually independently of overall mixture composition and imposed strain rate. An electrostatically controlled burner can manipulate a position of a flame between an oxidizer source and a fuel source by way of one or more electrodes configured to produce an electrostatic field proximate to one of the fuel source and the oxidizer source.

Abstract: A method for secure device-to-device communication using multilayered ciphers is provided. A selected cipher is employed to generate a pair of encryption/decryption keystreams for enabling multilayered encryption/decryption on a pulsed-index communication (PIC) packet(s). In examples discussed herein, a first layer encryption/decryption is performed by encrypting/decrypting a PIC data(s) (PD(s)) in the PIC packet(s) based on a first of the pair of encryption/decryption keystreams. In addition, a second layer encryption/decryption is performed by encrypting/decrypting selected control information (e.g., information related to encoding/decoding the PD(s)) in the PIC packet(s) based on a second of the pair of encryption/decryption keystreams. By performing multilayered encryption/decryption on the PIC packet(s), it is possible to defend against malicious attacks in single-channel device-to-device communication without compromising such key performance indicators (KPIs) as complexity, latency, power consumption, and footprint.

Abstract: In this work, we present a novel receiving device design for communications systems that incorporates multiple antennas at the transmitting device/receiving device. Unlike existing systems, the new system does not require prior knowledge of the channel state information (CSI) at the receiving device side to extract the information symbols from the received signal. Consequently, complexity reduction and bit error rate improvement can be jointly achieved. Moreover, the new system may offer spectral efficiency enhancement since it does not require nulling to prevent the pilot symbols as in the case of conventional systems. The results obtained show that in certain scenarios the proposed system can offer up to 15 dB of bit error rate improvement over conventional systems. Moreover, the new system can provide about 16.6% of the spectral efficiency improvement.

Abstract: The present invention proposes a demodulator device, a receiver and a demodulation method for M-ary amplitude shift keying systems (MASK) that requires partial knowledge of the CSI, namely, the channel attenuation coefficient. Therefore, the new demodulator, receiver and demodulation method do not require the knowledge of the channel phase shift. Consequently, no complicated channel estimation techniques are required, and the system will be very robust to the system impairments such as phase noise, I-Q imbalance, etc. In this sense, the new technique is denoted as semi-coherent demodulation (SCD). To reduce the complexity of the new SCD, a suboptimal demodulator is derived which has much lower complexity than the optimal while providing almost the same error probability.
