    摘要: Various methods and devices are provided to improve wireless communications. In one method, a need for additional wireless service in a target area is detected (401). As part of a first-layer beamforming process, a signaling beam is directed (402) toward the target area. As part of a second-layer beamforming process, at least some inter-cell interference is canceled (403) in the target area. In another method, a wireless denial of service (WDoS) attack from a first wireless node is detected (501). A signaling beam is directed (502) toward the first wireless node to suppress signaling from the first wireless node. While suppressing this signaling, service is provided (503) to other wireless nodes.

    摘要: A method for the polarization independent frequency domain equalization (FDE) chromatic dispersion compensation on polarization multiplexing (POLMUX) coherent systems. Operationally, time domain signals are converted to frequency domain signals such that time domain convolution can be done as simple multiplications in the frequency domain. These frequency domain signals then converted back to time domain for subsequent use. The input signal size and FFT size are advantageously designed so that the output signals can be continuous with some overlap between two successive frames.

    摘要: Methods and systems for evaluating checker quality of a verification environment are provided. In some embodiments, an overall sensitivity for the verification environment and an individual sensitivity for a respective checker are calculated. The overall sensitivity is a probability that a plurality of problematic design behaviors, which are propagated to a checker system including at least one checker, can be detected by the verification environment. The individual sensitivity is a probability that a plurality of problematic design behaviors, which are propagated to at least one specific probe among a plurality of probes of a design, can be detected by the checker corresponding to the specific probe. The overall checker sensitivity numbers can show the robustness of the check system. The individual checker sensitivity can guide the user which individual checker or checkers to improve.
