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： The present invention relates generally to methods and apparatus for optical wireless communication, and in particular to wireless optical delivery of a video signal. In one embodiment, a wireless optical video system (100) in which video content (e.g. , DVI or HDMI) is transmitted wirelessly between a digital video source (110) and a display device (150). This wireless optical communication is accomplished using a laser (520), encoded with the digital video data, directed from an optical transmitter (120) to an optical receiver (140). In another embodiment, the data to be communicated includes high-definition video content.

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.
摘要翻译：通过在环境操作条件的某个预定范围内改变环境操作条件，通过提供来自待校准的天线阵列的一个或多个测试信号到接收传感器来校准天线阵列。这些测试信号的信号特性可以由接收传感器或相关频谱分析仪测量，并且可以类似地测量提供测试信号的环境操作条件。此后，每个天线阵列的元件的信号偏移可以被确定为测量的环境操作条件的函数。然后可以将对应于这些信号偏移的校准信息存储在天线阵列的存储器中，以在天线阵列的操作期间使用。该校准信息可以是查找表或曲线拟合方程式的形式。
