  • Patent number: 11438089
    Abstract: Systems and methods for detecting and protecting against phase manipulation during AoA or AoD operations are disclosed. For AoA operations, the network device receiving the constant tone extension (CTE) generates an antenna switching pattern, which may be randomly generated. The network device then receives the CTE using a plurality of antenna elements. In one embodiment, the network device compares the phase of portions of the CTE signal received that utilize the same antenna element. If the phase of these portions differs by more than a threshold, the network device detects a malicious attack and acts accordingly. In another embodiment, if the AoA algorithm cannot determine the angle of arrival, the network device detects a malicious attack and acts accordingly. For angle of departure operations, the network device that transmits the CTE signal generates the antenna switching pattern and transmits it to the position engine, which performs the comparisons described above.

  • Patent number: 10382189
    Abstract: Embodiments of the present invention provide a method, an apparatus, and a system for multi-carrier OFDM duplex transmission, and relate to the communications field, so as to solve the problem where spectrum duplex transmission cannot be normally performed due to interference that is generated by an echo signal transmitted by using an OFDM technology. The method for multi-carrier OFDM duplex transmission includes: performing, on at least one OFDM subcarrier channel, sending and receiving of a near-end OFDM signal; obtaining a carrier phase difference between a near-end echo OFDM signal and a far-end OFDM signal; and performing a phase adjustment for the near-end OFDM signal according to the carrier phase difference.

  • Patent number: 10361783
    Abstract: Embodiments of the disclosure relate to digital interface modules (DIMs) for flexibly distributing digital and/or analog communications signals in wide-area analog distributed antenna systems (DASs). In this regard, in one aspect, a DIM is a multi-functional device capable of distributing the digital and/or analog communications signals to a local-area DASs in the wide-area DAS. The DIM comprises a digital communications interface for coupling with a digital signal source, an analog local distribution interface for coupling with an analog signal source, and at least one digital remote distribution interface for coupling with a head-end unit (HEU) of the local-area DAS. By employing the DIM in the wide-area DAS, it is possible to flexibly reconfigure the wide-area DAS for distributing digital and/or analog communications signals over the digital communications mediums.

  • Patent number: 10333690
    Abstract: Methods, apparatus, and systems for calibration and correction of data communications over a multi-wire, multi-phase interface are disclosed. In particular, calibration is provided for data communication devices coupled to a 3-line interface. The calibration includes generating and transmitting a calibration pattern on the 3-line interface, where the generation of the pattern includes toggling two of three interface lines from one voltage level to another voltage level over a predetermined time interval. Furthermore, the generation of the pattern includes maintaining a remaining third interface line at a common mode voltage level over the predetermined time interval, wherein only a single transition occurs for the predetermined time interval. Calibration data may then be derived in a receiver device using the transmitted calibration pattern.

  • Patent number: 10334567
    Abstract: A remote radio head unit (RRU) system for achieving high data rate communications in a Distributed Antenna System is disclosed. The Distributed Antenna System is configured as a Neutral Host enabling multiple operators to exist on one DAS system. The present disclosure enables a remote radio head unit to be field reconfigurable and support multi-modulation schemes (modulation-independent), multi-carriers, multi-frequency bands and multi-channels. As a result, the remote radio head system is particularly suitable for wireless transmission systems, such as base-stations, repeaters, and indoor signal coverage systems.

  • Patent number: RE47190
    Abstract: A method of mapping symbols of a physical control format indicator channel (PCFICH) is described. A start position of a resource element to map the symbols for the PCFICH is determined by flooring a value, obtained by multiplying the number of resource blocks by a variable proportional to a symbol index for the PCFICH and then dividing the multiplied result by 2, wherein the resource blocks are transmitted in downlink. The symbols are mapped in the start position. Therefore, a problem of wasting resource elements or not being able to implement mapping can be solved by applying a simple mapping rule while mapping symbols of the PCFICH.
