Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: An in-phase and guadrature (IQ) imbalance error-correction method includes estimating, on the basis of a constellation error in a received orthogonal frequency division multiplexing (OFDM) signal, an extent of an I/Q imbalance error, caused by direct IQ conversion of the received OFDM signal. On the basis of that extent, an equalizing transformation that reduces that error is estimated.

The improved video decoder then separates luminance information and chrominance information of the digitized video signal in a dimension that has a constancy value below a predetermined threshold level. Lastly, the improved video decoder optionally converts the separated luminance information and chrominance information into an output format that conforms to input requirements of the NTSC/PAL television.

Abstract: A first signal containing a noise characteristic such as ingress, a data signal component, and a known sequence of symbols is transmitted from a client to a headend via a transmission channel within a communication network. A model of the transmission channel in the absence of the noise characteristic is then generated, the known sequence of symbols is applied to the transmission channel model, and the output of the transmission channel model is compared to the received signal to dynamically estimate the noise characteristic. The dynamically estimated noise characteristic is then used to modify the signal either at the client or the headend to reduce the impact of the noise characteristic on the transmitted data.
