    摘要: The frequency of a digital data signal, such as a digital video signal, is intentionally varied or hopped before being sent over a network. This frequency hopping may be performed in accordance with a frequency hopping pattern shared with only intended receivers. The digital data signal may be further intentionally pre-distorted in accordance with a pre-distortion pattern which is also shared with only intended receivers. The frequency hopping and/or the pre-distortion patterns may be used to vary the frequency and modulation, respectively, on a periodic basis, such as a symbol-by-symbol or packet-by-packet basis.

    摘要: Antenna arrays are calibrated by providing one or more test signals from the antenna array to be calibrated to a receiving sensor while varying ambient operating conditions over some predetermined range of ambient operating conditions. The signal properties of these test signals may be measured by the receiving sensor or associated spectrum analyzer, and the ambient operating conditions under which the test signals are provided may be similarly measured. Thereafter, signal offsets for each of the antenna array's elements may be determined as a function of the measured ambient operating condition. Calibration information corresponding to these signal offsets may then be stored in a memory of the antenna array for use during operation of the antenna array. This calibration information may be in the form of a lookup table or a curve-fitting equation.

    摘要: In a home system in which a TV receives video from various sources over directional wireless links such as 60 GHz links, a mirror apparatus is provided that can be configured to physically steer a signal toward a receiver on the TV to optimize received signal strength. In this way, RF energy that otherwise would be radiated in non-productive directions away from the receiver is reflected toward the receiver.

    摘要: The return channel in a multiple-input and multiple-output (MIMO) communication system is used to provide signal information on an individual-channel basis. In one embodiment, in a controlled factory environment, this information may be used to incrementing up or down the variable gain amplifier and/or the power amplifier of a MIMO transmitter and/or receiver so as to generate a default signal power offset to be used during normal operation. Thereafter, such signal information may similarly be provided via the return channel and used to further adjust the transmit parameters to account for location-specific signal conditions.

    摘要: One embodiment of the invention relates to a system for enhancing reception of radio-frequency (RF) signals by an audio-video device such as a high-definition television. The system comprises an audio-video device including a radio-frequency (RF) receiver to receive incoming EF signals, and an RF reflective element. The RF reflective element is positioned to reflect RF signals towards the audio-video device. The RF reflective element is at least partially imbedded with RF reflective materials to reflect undetected, RF signals destined for the audio-video device back to the RF receiver.
