Abstract: A multi-polarization millimeter wave (mmWave) transmitter/receiver (TX/RX) architecture with shared power amplifiers (PAs) is provided. This architecture provides a transceiver which uses shared PAs to reduce the number of TX and PA stages required for multi-polarization transmission in mmWave radio frequency (RF) devices. Embodiments provide an array of switching channels which selectively connect a shared TX and shared PA to two or more antennas in antenna arrays having different polarizations (e.g., a dipole antenna array and a patch antenna array). This approach provides a dual polarization or multi-polarization mmWave transceiver having a reduced number of components which results in a smaller size, improved power efficiency, and improved power heat dissipation.

Abstract: A receiver and a receiving method of the receiver such that monolithic integration of multiple receiving channels can be implemented. The receiver includes a zero intermediate frequency channel, performing in-phase/quadrature (IQ) down conversion on a radio frequency signal at a first frequency band using a frequency division or frequency multiplication signal of a first signal, and a superheterodyne channel, performing down conversion on a radio frequency signal at a second frequency band using the frequency division or frequency multiplication signal of the first signal, where the first frequency band is different from the second frequency band. The zero intermediate frequency channel and the superheterodyne channel use a same oscillation signal or a same frequency division or frequency multiplication signal of the oscillation signal, thereby monolithic integration of multiple receiving channels can be implemented.

Abstract: Technologies directed to antenna disconnection detection of distributed radio frequency (RF) ports in a wireless network are described. One method receives data from the wireless devices and generates an RSSI matrix including multiple elements, each storing a receive signal strength indicator (RSSI) value indicative of a signal strength of a wireless link between a transmitter-receiver pair. The method identifies a characteristic pattern in the RSSI matrix. The characteristic pattern includes i) two or more RSSI values in a same row being less than the threshold value and ii) two or more RSSI values in a same column being less than the threshold value. The method stores an indication that an antenna is disconnected from an RF port and sends a command to the second wireless device that causes the second wireless device to disable a radio that is coupled to the RF port.

Abstract: A system and method is provided for a web services-based data transfers. A data power component translates a service request in a first format received from a first computing device into a translated service request in a second format compatible with a web service. The translated service request includes converted freight data associated with a set of items structured for storage within one or more database(s) associated with a second computing device. The translated service request is a request to load the freight data onto the database(s). The translated service request is transmitted to the web service. In response, the data power component receives a response from the web service indicating whether the freight data is successfully loaded onto the database(s). The data power component translates the response from the second format into the first format. The translated response is returned to the first computing device.

Abstract: A radio-frequency module (20) includes a module substrate (50) and a filter (21). The filter (21) has a sensitive GND electrode and a non-sensitive GND electrode that are connected to an external-connection ground terminal of the module substrate (50), and parallel-arm resonators. An inductance component generated by the sensitive GND electrode shifts, by a first shift amount, an attenuation pole that corresponds to a parallel-arm resonator and that is formed near a pass band. An inductance component generated by the non-sensitive GND electrode shifts, by a second shift amount, an attenuation pole that corresponds to a parallel-arm resonator and that is formed near the pass band. The first shift amount is larger than the second shift amount, and the distance between the sensitive GND electrode and the external-connection ground terminal is smaller than the distance between the non-sensitive GND electrode and the external-connection ground terminal.

Abstract: A receiver signal is sampled at a sampling rate equivalent to a chip rate at which chips of a known signal are timed. The resulting receiver signal samples are segmented into receiver signal segments, which are filtered by respective matched filters that are matched to known signal segments segmented from the known signal. Indexes are assigned to elements of the resulting filter response sequences to define an array thereof. Frequency transforms are computed of elements of the filter response sequences in respective columns of the array. Indexes are assigned to elements of the resulting frequency response sequences to define another array thereof. Channel effects imparted on a radio signal are jointly estimated from characteristics of the other array at which at least one local maximum is located.

Abstract: The system, products, and methods disclosed herein relate to an improved configuration for geographically dispersed data restart (“GDDR”) systems. Specifically, the teachings herein ensure a particular GDDR instance does not react to messages issued from address spaces outside of its affinity group. We use the term message “affinity group” to mean the combination of a particular GDDR instance and its set of Mainframe Enablers started tasks. By ensuring that the particular GDDR instance does not react to messages intended for recipients outside of its affinity group, we improve computer functionality and efficiency by facilitating further partitioning of the logical partition. Once the logical partition is further partitioned into additional address spaces, it is possible to run Mainframe Enablers and/or additional GDDR instances independent of the particular GDDR instance of concern.
