  • Patent number: 8885581
    Abstract: Neighbor cell hearability can be improved by including an additional reference signal that can be detected at a low sensitivity and a low signal-to-noise ratio, by introducing non-unity frequency reuse for the signals used for a time difference of arrival (TDOA) measurement, e.g., orthogonality of signals transmitted from the serving cell sites and the various neighbor cell sites. The new reference signal, called the TDOA-RS, is proposed to improve the hearability of neighbor cells in a cellular network that deploys 3GPP EUTRAN (LTE) system, and the TDOA-RS can be transmitted in any resource blocks (RB) for POSCH and/or MBSFN subframe, regardless of whether the latter is on a carrier supporting both PMCH and POSCH or not. Besides the additional TDOA-RS reference signal, an additional synchronization signal (TDOA-sync) may also be included to improve the hearability of neighbor cells.

  • Patent number: 8817590
    Abstract: In general, according to an embodiment, a wireless transmitter includes a plurality of coding and modulation modules to apply corresponding coding and modulation algorithms to input information blocks. A discrete Fourier transform (DFT) precoder applies DFT processing to outputs of the coding and modulation modules, and an inverse fast Fourier transform (IFFT) module receives a DFT output of the DFT precoder, which is mapped to different subcarriers according to the resource allocation indicated by the base station, and applies IFFT processing to the DFT output. An output processing stage produces output signals based on the output of the IFFT module to transmit wirelessly to a wireless receiver. In a different implementation, the outputs of the coding and modulation modules can be provided to an IFFT module to produce IFFT-processed output information.

    Abstract: The present disclosure provides for an improved application of signal strength weightings in an SDMA sectored cellular network. The improved signal strength weightings application is conducted through the improved selection of weightings from a new codebook subset or by the selection of weightings from a larger codebook subset. In a further embodiment, an antenna beam index or bit map can be used to select the best beam(s) in an SDMA sectored cellular network. In another embodiment, a field or factor in an uplink or downlink transmission packet can designate which directional transmission beam is best suited for the transmission or when the directional transmission beam should be activated.

  • Patent number: 8170124
    Abstract: An MPEG-4 system with error concealment is provided for video service under the network with packet loss. The MPEG-4 system includes an encoder and a decoder. The encoder uses an intra-refreshment technique is used to make coded bitstream more robust against noise in order to stop error propagation. The rate-distortion optimization criterion is also introduced to adaptively update in synchronization with intra-coded blocks adaptively based on the true network condition with minimal overhead. The Lagrange multiplier is modified to achieve the best rate-distortion balance. In addition, a decoder loop is used in the encoder and is synchronized with the true decoder to achieve the best performance and avoid mismatch with the decoder used in the MPEG-4 system. The decoder is able to achieve resilient decoding from any kind of noise and enhance the reconstructed image quality with spatial and temporal hybrid concealment method. The result shows that a 3.65-9.

  • Publication number: 20110166045
    Abstract: Plasmonics-active nanostructure substrates—developed on a wafer scale in a reliable and reproducible manner such that these plasmonics-active nanostructures have nano-scale gaps (that include but are not limited to sub-10 nm gaps or sub-5 nm gaps) that provide the highest EM field enhancement between neighboring plasmonics-active metallic or metal-coated nanostructures. The plasmonics-active nanostructure substrates relate to environmental sensing based on SERS, SPR, LSPR, and plasmon enhanced fluorescence based sensing as well as for developing plasmonics enhanced devices such as solar cells, photodetectors, and light sources. Controllable development of sub-2 nm gaps between plasmonics-active nanostructures can also be achieved. Also, the size of the nano-scale gap regions can be tuned actively (e.g., by the application of voltage or current) to develop tunable sub-5 nm gaps between plasmonic nanostructures in a controllable manner.
