  • Patent number: 8550640
    Abstract: An antiglare film with various inner and outer haze includes a transparent substrate, and an antiglare coating layer formed by coating an antiglare coating solution on the transparent substrate. The antiglare coating solution further includes a resin, resin-philic light-scattering particles and resin-phobic light-scattering particles. The resin-philic light-scattering particles and the resin-phobic light-scattering particles respectively have different functional groups on the surfaces thereof. The resin-philic light-scattering particles do not repel the resin and thus are distributed inside the antiglare coating layer. The resin-phobic light-scattering particles repel the resin and thus are distributed on the surface of the antiglare coating layer, so that the inner and outer haze of an antiglare film can be effectively controlled via adjusting the proportion of the resin-phobic to resin-philic light-scattering particles.

  • Patent number: 8416869
    Abstract: In a peak-to-average power ratio (PAPR) reduction method for an orthogonal frequency division multiplexing (OFDM) system based on path finding, the method applied to the OFDM system uses an ant colony optimization (ACO) algorithm and a PTS to reduce a PAPR value, and an area of a computing circuit. In a simulated result, the method can reduce the PAPR effectively, and can be executed by a lower level of complexity of the computation. To solve a large matrix of the PTS, an ant colony optimization algorithm is used for calculating phase rotation vectors of a better quality effectively to achieve the effects of improving the performance, overcoming the high level of complexity of the computing circuit, and reducing the large area of the computing circuit.

  • Patent number: 8401057
    Abstract: An OFDM-based relay-assisted channel estimation method enables a composite channel (source-relay-destination) to be disintegrated into a source-to-relay channel and a relay-to-destination channel and separately estimated at the destination node in a relay-assisted way. A relay-amble signal is added to a sub-frame when the relay node is forwarding the amplified signals from the source node. Through the relay-amble signal, the second channel estimation from the relay node to the destination node is performed to obtain a second channel coefficient, and then uses an ML (Maximum Likelihood Estimator) algorithm to estimate a first channel coefficient from the source node to the relay node. After having estimated the coefficients of the two channels, the optimum diversity combining is performed at the destination node to improve accuracy of received data.
