    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： Methods and apparatus for optical wireless communication. In one embodiment, a wireless optical video system in which video content (e.g., DVI or HDMI) is transmitted wirelessly between a digital video source and a display device. This wireless optical communication is accomplished using a laser, encoded with the digital video data, directed from an optical transmitter to an optical receiver. In another embodiment, the data to be communicated includes high-definition video content.

    摘要： A quantized channel rate and corresponding rate multiplier is determined on a transmitter-side of a communication system based on a measured minimum required bandwidth. In certain embodiments, the quantized data rate may be an integer multiple of the system's reference clock. The determined rate multiplier is then transmitted to the receiver-side at a default data rate prior to or near the beginning of a data transmission session, such as upon initialization. Prior to transmission, the data stream may be padded with some determined amount of null data such that the actual transmitted data rate is approximately equal to the quantized channel rate, and the receiver-side can readily recover the data clock using its known reference clock and the previously-provided rate multiplier.
