摘要： A system and method for automatically directing a communication antenna to point to a desired wireless communication transceiver, is presented herein. The system includes a position location receiver, which receives signals indicating the position location information of the antenna and a position location transmitter and a processing mechanism, which determines calibration information of the antenna. The calibration information is achieved by first establishing a reference vector between the location of the antenna and position location transmitter and establishing a vector reference space and then calculate the necessary elevation and azimuthal components, within the vector reference space, to identify the proper calibration of the antenna. Once the calibration information has been determined, an alignment mechanism automatically orients the antenna. The alignment mechanism then automatically directs the oriented antenna to point to the wireless transceiver, based on the directional location information of the wireless transceiver.

摘要： At least one feature provides a way to perform point-to-multipoint transmissions using adaptive or directional antennas while reducing antenna pattern distortion. Generally, rather than transmitting the same waveform to two or more receivers, an information-bearing signal is transformed into different decorrelated waveforms and each decorrelated waveform is transmitted to a different receiver. In one implementation, an information-bearing signal is transformed into two decorrelated signals such that their crosscorrelation, or autocorrelation of the information-bearing signal, is zero or very small. Such decorrelation may be achieved by sending a first signal to a first receiver while sending a second signal, having a radio frequency spectrum that is the spectrally inverted version of the first signal, to a second receiver. In another implementation, a first signal is transmitted to a first receiver and is also transmitted to a second receiver with a time delay.
摘要翻译：至少一个特征提供了使用自适应或定向天线执行点对多点传输的方式，同时减少天线模式失真。通常，不是将相同的波形发送到两个或更多个接收机，而是将信息承载信号变换成不同的去相关波形，并将每个去相关的波形发送到不同的接收机。在一个实现中，信息承载信号被变换成两个去相关信号，使得其信息载运信号的互相关或自相关为零或非常小。这种去相关可以通过向第一接收机发送第一信号来实现，同时向第二接收机发送具有作为第一信号的频谱反转版本的射频频谱的第二信号。在另一实现中，第一信号被发送到第一接收机，并且还以时间延迟被发送到第二接收机。
