  • Publication number: 20210247484
    Abstract: Disclosed are methods and systems for a WLAN device operating on DFS channels to calibrate the PRI as well as delays between partial pulses of received radar pulses that are impaired due to channel and filtering effects. The calibrated PRI may approximate the PRI of the transmitted pulses. The calibrated delay between the partial pulses estimates the interval between two partial pulses that originally belong to the same transmitted pulse. Using the calibrated PRI and the calibrated delay between partial pulses, the WLAN device may reconstruct the original pulses from received impaired pulses even when the impaired pulses are delayed and partial pulses of the original pulses. The WLAN device may use the calibrated results to correct the shortened PW and varying PRI of the impaired pulses to restore the partial pulses to their full PW with a relatively uniform PRI, increasing the probability of detecting the radar signals.

  • Publication number: 20210102992
    Abstract: An adjustable probe device includes fixed and movable probes, at least one of which is a signal probe having a coaxial structure. The movable probe is linearly slidable with a ground unit thereof abutted against a ground unit of the fixed probe. Another adjustable probe device includes a first movable probe for being grounded, and fixed and second movable probes both having a coaxial structure. Any of the two movable probes is selectable to be a functioning probe in a way that the contact ends of the functioning and fixed probes are located on a same plane for contacting two pads of a DUT at the same time, and the functioning probe is linearly slidable with a ground unit thereof abutted against a ground unit of the fixed probe. As a result, the probe interval is adjustable, lowering the cost of the impedance testing apparatus for circuit boards.

  • Publication number: 20080031386
    Abstract: A method, algorithm, architecture, circuits, and/or systems for robust radar signal detection for wireless communications are disclosed. In one embodiment, a method of detecting a predefined signal pulse event in a wireless network device can include the steps of: (i) comparing a power of a received signal pulse to a predetermined power threshold of a predefined signal; (ii) determining a duration of the received signal pulse when the power of the received signal pulse is greater than the predetermined power threshold; and (iii) indicating an occurrence of the predetermined signal pulse event when the duration of the received signal pulse is between first and second predetermined duration thresholds of the predefined signal. The predefined signal pulse event can be a radar signal pulse, for example. Embodiments of the present invention can advantageously provide a reliable and simplified approach for radar signal detection suitable for wireless network devices.

  • Patent number: 7039132
    Abstract: This invention provides a method for bit detection of the GFSK signals at the receiver end. The bit detection is done digitally after the carrier is removed. It employs differential detection incorporated with decision feedback, which uses previous one (so-called on-bit differential detection), or two (so-called two-bit differential detection) bits as correcting information. In addition, synchronization for bit timing and frequency offset resulted from clocks between the transmitter and receiver are also performed with or without preamble as prior information. If preamble is available, the bit timing and frequency-offset bias are estimated from the preamble, which is the case of this present invention. If preamble is not available, this information is estimated directly from the unknown received signals. Once the information about the bit timing and frequency offset is obtained, it is used for the following bit detection.
