  • Publication number: 20160212002
    Abstract: The disclosure discloses a method and device for performing peak clipping to multiple carrier waves, the method includes: according to carrier wave number of configured multiple carrier waves, signal bandwidth and occupied bandwidth of each carrier wave, obtaining total signal bandwidth and total occupied bandwidth of the corresponding carrier waves; according to the total signal bandwidth and the total occupied bandwidth of the multiple carrier waves, generating a digital filter with set order, and obtaining filter coefficient of the digital filter; taking the filter coefficient as a peak clipping coefficient and using the peak clipping coefficient to perform peak clipping to the peak-to-average ratio signals of the carrier waves. By the disclosure, the complexity of the generation of the peak clipping coefficient is simplified, the deterioration degree of EVM is reduced, and the distortion degree of signals is also reduced.

  • Patent number: 9398314
    Abstract: Architecture for enhancing the compression (e.g., luma, chroma) of a video signal and improving the perceptual quality of the video compression schemes. The architecture operates to reshape the normal multimodal energy distribution of the input video signal to a new energy distribution. In the context of luma, the algorithm maps the black and white (or contrast) information of a picture to a new energy distribution. For example, the contrast can be enhanced in the middle range of the luma spectrum, thereby improving the contrast between a light foreground object and a dark background. At the same time, the algorithm reduces the bit-rate requirements at a particular quantization step size. The algorithm can be utilized also in post-processing to improve the quality of decoded video.

  • Publication number: 20150358922
    Abstract: Disclosed is a method and a system for switching pre-distortion coefficients, which is used to solve the problem of interference with neighbor cells due to the inferior pre-distortion coefficients. The method comprises: presetting a primary table and a standby table, wherein the primary table stores default pre-distortion coefficients and the standby table stores updated pre-distortion coefficients; when a data source of a pre-distortion processor adopts the standby table, adopting the updated pre-distortion coefficients to perform parameter output processing to acquire pre-distortion parameters, and conveying the pre-distortion parameters and an input signal to the pre-distortion processor to process to acquire pre-distortion signals; conveying the pre-distortion signals through various signal processors to acquire a first signal, and determining the power data of the first signal; and based on the comparing result of the power data of the first signal and a setting range, there are different actions.

  • Patent number: 8964829
    Abstract: Techniques to perform fast motion estimation are described. An apparatus may comprise a motion estimator operative to receive as input a current frame and a reference frame from a digital video sequence. The motion estimator may generate and output a motion vector. The motion vector may represent a change in position between a current block of the current frame and a matching reference block of the reference frame. The motion estimator may utilize an enhanced block matching technique to perform block matching based on stationary and spatially proximate blocks. Other embodiments are described and claimed.
