    摘要: Performance of transport protocols over a mobile data network is improved by a mobile accelerator, which performs protocol optimizations on-the-fly without requiring any modification to server or client protocol implementations in the operating systems of the server or client. The proposed mobile accelerator is compatible with existing TCP protocol implementations at the server and the client device, without server/client OS modification.

    摘要: Methods and apparatus for selecting samples for secondary synchronization signal (SSS) detection are described. Several alternatives are provided for efficient cell identifier detection. In a first alternative, multiple bursts of a signal received from a cell are sampled with non-uniform spacing between sampling intervals to determine a sequence for cell identification. In a second alternative, samples of a first and a second signal received from a stronger cell are cancelled, and a sequence for detecting a weaker cell is determined by reducing effects of the samples of a third signal received from the weaker cell which do not overlap with the primary synchronization signal (PSS) or SSS of the stronger cell. In a third alternative, a sequence for detecting a weaker cell is determined by reducing effects of any sampled bursts that correspond to a high transmission power portion of a signal from a stronger cell.

    摘要: Providing for secondary synchronization encoding utilizing a primary synchronization channel (P-SCH)-related scrambling code is described herein. Scrambled secondary synchronization codes (SSCs) can be assigned to multiple base stations of a radio access network (RAN). By way of example, PSC-based scrambling codes can be created from a plurality of M-sequences generated from a common polynomial expression. Further, an SSC codebook is provided that selects sequence pairs of a sequence matrix for generating SSCs. Selection can be based on transmission characteristics of resulting SSCs, providing reduced interference in planned, semi-planned and/or unplanned mobile deployments.

    摘要: A system for use in a gasification system, comprises a solid pump that delivers a pressurized fuel and a high-pressure transition vessel. The transition vessel comprises a first inlet connected to an outlet of the solid pump so that all of the fuel from the solid pump passes through the transition vessel, a second inlet for connection to a conveyance gas line, and an outlet through which the fuel is transported to a gasifier. The transition vessel is elongated in the direction of a flow so that a conveyance gas introduced through said conveyance gas line plus the pressure difference carries the fuel to the gasifier.

    摘要: Systems and methods are provided to generate a set of synchronization channel sequences that optimize time and frequency acquisition. A set of root indices of Zadoff-Chu sequences in a first domain (e.g., time domain) that optimize a performance metric or merit factor are identified. An optimal index is determined that also optimizes a performance metric in a reciprocal domain (e.g., frequency domain). Optimal indices satisfy a centro-symmetric relationship with respect to a half-value of sequence length: When 1 is an optimal index, N−1 is also an optimal root index. For sequences of length Q2=N, a base sequence generated with an optimal sequence can be utilized to generate at least two disparate optimal sequences through sign-flip, conjugation, and periodic modulation operations.
