20150043583 | Load Balancing and Session Persistence in Packet Networks - Methods and systems for performing load balancing and session persistence in IP (e.g., IPv6) networks are described herein. Some aspects relate to a destination options extension header that may be defined as a load balancing session persistence option (LBSPO) for storing a client identifier and a server identifier for each of a client and a server during a session.

Thus, the photonic crystal can act as a resonator that supports single-mode output from the PCSEL over a larger area than is possible with conventional PCSELs, which have quadratic band edge dispersion. Because output power generally scales with output area, this increase in output area results in higher possible output powers. | 2015-02-12 |

20150043676 | SHORT GUARD INTERVAL WITH GREEN FIELD PREAMBLE - Systems, methods, and other embodiments associated with a single stream wireless communication with a greenfield preamble that uses a short guard interval are described. According to one embodiment, a wireless communication device includes a transmitter configured to generate an orthogonal frequency-division multiplexing (OFDM) signal that comprises (i) a preamble and (ii) a data segment. The data segment follows the preamble. The data segment includes a plurality of data symbols that are each respectively preceded by a corresponding guard interval. A first guard interval preceding a first data symbol in the data segment has a first duration of time and each of the corresponding guard intervals that precede the remaining data symbols subsequent to the first data symbol in the data segment have a second duration of time. The second duration of time is shorter than the first duration of time. | 2015-02-12 |
20150043677 | ENHANCED SIGNAL INTEGRITY AND COMMUNICATION UTILIZING OPTIMIZED CODE TABLE SIGNALING - In various embodiments, a computer-implemented method for optimized data transfer utilizing optimized code table signaling is disclosed. In one embodiment, a computer-implemented method comprises receiving, by a processor, a digital bit stream and transforming, by the processor, the digital bit stream to an encoded digital bit stream. The encoded digital bit stream comprises at least one of a gateway channel, a composite channel, or a data channel, and any combination thereof. The computer-implemented method further comprises providing, by the processor, the encoded digital bit stream to a transmission system for transmission and establishing, by the processor, signal integrity by utilizing pre-coordinated, pre-distributed information to limit the transmission to an intended sender-receiver pair. The intended sender-receiver pair comprises the pre-coordinated, pre-distributed information. | 2015-02-12 |
20150043678 | SCALABLE DIGITAL PREDISTORTION SYSTEM - The scalable digital predistortion system provides a behavioral model that can be used to model and compensate for the nonlinear distortions of power amplifiers and transmitters. The predistorter and update algorithms make the model/DPD scalable in terms of signal bandwidth and average power, allowing for low complexity update following changes in the signal's bandwidth and/or power level. Experimental validation carried on a 300 Watt Doherty power amplifier shows that the scalable model and the predistorter architecture achieve performance similar to their conventional counterpart. However, the present model/predistorter requires the update of up to 50% fewer coefficients than the conventional model/predistorter. | 2015-02-12 |
20150043679 | OFDM MODULATED WAVE TRANSMITTER APPARATUS, OFDM MODULATED WAVE TRANSMISSION METHOD, AND PROGRAM - In an orthogonal frequency division multiplex (OFDM) modulated wave transmitter apparatus, a symbol mapping circuit and a serial/parallel (S/P) converter generate an OFDM symbol signal from transmission data. An inverse fast Fourier transform (IFFT) circuit, a parallel/serial (P/S) converting and guard interval (GI) adding circuit, a timing adjusting circuit, a digital/analog (D/A) converter, a frequency converter, a local oscillator and an analog filter generate an OFDM modulated wave signal from the OFDM symbol signal. A power amplifier (PA) control circuit limits a band of the OFDM symbol signal and generates a PS control signal and a PA control signal. A PA designates a voltage supplied from a DC/DC converter as a PS voltage and amplifies and outputs the OFDM modulated wave signal based on the PA control signal. | 2015-02-12 |
20150043680 | Rhombic-QPSK Modulation for Improved Tolerance to Nonlinearity in Fiber Communication Systems - This invention proposes an alternative modulation format for channels that present improved performance when such channels co-propagate with existing intensity modulated channels. This modulation format is named Rhombic-QPSK (R-QPSK) and it is designed in such a way that it presents more tolerance to phase noise created by the nonlinear interaction with the legacy channels. | 2015-02-12 |
