    摘要： A method and apparatus for platform noise estimation and mitigation are provided. An embodiment of a method for mitigating noise may include receiving a data signal in a system platform, where the data signal includes a received pseudo noise sequence. Noise on the system platform may be estimated based on the received pseudo noise sequence. In some embodiments the noise on the system platform may be mitigated based on the noise estimate for the system platform.

    摘要： A base station for a wireless communication system has an antenna system that provides a downstream transmit pattern partitioned into azimuthal sectors and an upstream receive pattern partitioned into azimuthal sectors and elevation sectors. The base station has a transmitter connected to the antenna system to transmit a signal to a subscriber using the downstream transmit pattern, and a receiver connected to the antenna system for receiving a signal from the subscriber using the upstream receive pattern.

    摘要： Device, system, and method of mitigating interference to digital television signals. For example, an apparatus includes a diversity-based digital television receiver having a filter controller and at least first and second channel paths, wherein the first channel path includes a first Global System for Mobile communication (GSM) reject filter, the second channel path includes a second GSM reject filter, the second channel path is parallel to the first channel path, and the filter controller is to selectively switch an operational state of the first GSM reject filter.

    摘要： In one embodiment of the invention, a Fourier transform unit converts unsynchronized data received through multiple antennas to a frequency domain. Also, a spectrum estimation unit determines a power spectrum for the unsynchronized data. A notch filter removes data within a frequency band from additional unsynchronized data based on the power spectrum. A synchronization unit synchronizes the notch filtered data and a noise estimation unit determines a noise covariance matrix between the synchronized data received from multiple antennas. In addition, an equalization unit performs channel equalization on the synchronized data based on the noise covariance matrix.
