    Abstract: A communication system (10B) comprises a signal generator (112), polarizer (102), signal combiner (123), transmitter (105), positioning device (120A), and controller (50A). The signal generator (112) converts first and second received data streams (113A, 113B) into respective first and second orthogonal linearly polarized signals (118A, 118B). The polarizer (102) is at a first rotation angle and converts first and second orthogonal linearly polarized signals (118A, 118B) into, respectively, a first right-hand-circularly polarized (RHCP) signal (122A) and first left-hand circularly polarized (LHCP) signal (122B), which are combined in signal combiner (123A) into a signal sent by transmitter (106) to a receiver (108). The positioning device (120A) adjusts the first rotation angle to substantially increase isolation between third and fourth orthogonal linearly polarized signals (124A, 124B) at the receiver (108). The controller (50A) performs the real-time analysis of transmission loss and directs the positioning device (120A) to adjust the first rotation angle.

    Abstract: Aspects of the present disclosure are directed to rule based switchable polarization techniques. In one aspect, a device may receive one or more RF signals. A packet error rate associated with the received one or more RF signals may be determined. A polarization switching circuit may determine if the measured PER is greater than a predetermined threshold PER. In response to the determination that the PER is greater than the predetermined threshold PER, the polarization switching circuit may change a polarization of the device.

    Abstract: An Adaptive Polarization Array (APA) Algorithm is described for adjusting the polarization orientation of antennas, such as Dual-polarized array antennas. The APA Algorithm searches to find a polarization state that maximizes a signal quality of a received signal in the presence of interfering signals and noise. The search facilitates adjustment of a polarization state of, for example, receive antennas to maximize a signal quality metric. A proxy metric having no local maxima other than the global maximum is used to search the polarization search domain to find a best polarization state.

    Abstract: Embodiments of the invention pertain to Radio Frequency Identification (RFID) method and system using an antenna array, an array controller, and control algorithms. Embodiments of the invention can induce strong radio-frequency (RF) excitation, for a given level of radiated RF power, at any point within an arbitrary inhomogeneous medium. For RFID applications, one typical inhomogeneous medium is an ensemble of cases on a pallet. Another typical medium is a warehouse environment having stored goods together with shelving and other material present. An embodiment of the invention is applicable to the process of reading battery-less, or 'passive' RFID tags, which rely on incident RF electromagnetic fields established by RFID readers to power the electronic circuitry within the tags.

    Abstract:  制御ループが切れたときに積分回路の積分内容が不定になるという問題を解決する直交偏波間干渉補償装置を提供する。  直交偏波間干渉補償器は、自偏波信号に含まれる位相雑音を補償するための補償信号を生成する。復調器は、自偏波信号に含まれる位相雑音を補償信号に基づいて、直交偏波間干渉を補償する。誤差検出器は、復調器にて補償された自偏波信号と、本来あるべき自偏波信号との位相差を示す誤差信号を生成する。位相雑音位相検出器は、補償信号と誤差信号とに基づいて、自偏波信号および異偏波信号の位相差を示す差分信号を生成する。積分回路は、差分信号を積分して積分信号を生成する。無限移相器は、積分信号に基づいて補償信号を調節する。制御回路は、無限移相器が調節した補償信号に基づいて、直交偏波間干渉があるか否かを判断し、直交偏波間干渉がない場合、積分信号が示す積分値を所定値に調整する。
