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.

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.
摘要翻译： 多输入多输出（MIMO）通信系统中的返回信道用于在单个信道的基础上提供信号信息。 在一个实施例中，在受控的工厂环境中，该信息可用于向上或向下递增MIMO发射机和/或接收机的可变增益放大器和/或功率放大器，以便产生待使用的默认信号功率偏移 正常运行时。 此后，类似地可以经由返回信道提供这样的信号信息，并且用于进一步调整发射参数以考虑位置特定信号条件。
