Abstract: A Bluetooth transmitter, a Bluetooth device, and a transmitter are provided. After being received by the transmitter, a transmission bitstream is modulated to generate a first-path modulated signal and a second-path modulated signal, which are up-converted to a first first-path up-converted signal, a second first-path up-converted signal, a first second-path up-converted signal, and a second second-path up-converted signal. The first first-path and the second first-path up-converted signals are corresponding to a first broadcast channel, and the first second-path and the second second-path up-converted signals correspond to a second broadcast channel. A first-path baseband signal is generated based on the first first-path and the second first-path up-converted signals, and a second-path baseband signal is generated based on the first second-path and the second second-path up-converted signals. A broadcast signal is generated based on the first-path and the second-path baseband signals.

Abstract: An embodiment of the present application discloses a global navigation satellite system (GNSS) integrated circuit (IC). The GNSS IC includes a GNSS module, a memory and a processor. The GNSS module is arranged operably to receive a to-be-identified broadcast GNSS signal. The memory is arranged operably to store a plurality of ephemeris aiding data candidates, wherein the ephemeris aiding data candidates are not provided by the GNSS module. The processor is arranged operably to determine whether the to-be-identified broadcast GNSS signal is a spoofing signal based on an ephemeris aiding data reference in the ephemeris aiding data candidates.

Abstract: A wireless communication device includes a receiver circuit, a phase shift control circuit, and a digital phase-locked loop (DPLL) circuit. The receiver circuit includes a down-converter circuit that is used to apply down-conversion to an input signal according to a local oscillator (LO) signal. The phase shift control circuit is used to generate a phase shift signal. The DPLL circuit is used to generate the LO signal locked to an initial frequency under a frequency-lock state. In response to the phase shift signal, the DPLL circuit is further used to make the LO signal have a different frequency without leaving the frequency-lock state.

Abstract: The invention relates to a method, a non-transitory computer-readable storage medium, and an apparatus for receiving Bluetooth packets and correcting error bits therein. The method, which is performed by a processing unit, includes: receiving Bluetooth packets from radio frequency (RF) signal; verifying a unique synthesized packet with a first checksum thereof when the unique synthesized packet can be generated from the Bluetooth packets; generating synthesized packet candidates according to at least one inconsistent bit between the Bluetooth packets and verifying each synthesized packet candidate with a second checksum thereof when the unique synthesized packet cannot be generated from the Bluetooth packets; and transmitting a synthesized packet that has passed a verification to a program module for an application when the unique synthesized packet or any of the synthesized packet candidates passes the verification.

Abstract: The present invention relates to an active noise cancellation integrated circuit for stacking at least one anti-noise signal and at least one non-anti-noise signal, an associated method, and an active noise cancellation headphone using the same. The method is applicable to an audio playback device with at least one ANC filtering unit and at least one non-ANC filtering unit. The method includes: acquiring a non-anti-noise signal from a non-ANC filtering unit; generating a decoupled signal by processing the non-anti-noise signal with the transfer function of a physical channel and operations of an ANC filtering unit; performing a signal superposition, wherein an anti-noise signal from the ANC filtering unit is superposed with the decoupled signal; and performing an audio playback based on the superposed signal and an audio signal such that noise is eliminated.

Abstract: The present invention relates to an active noise cancellation integrated circuit for stacking multiple anti-noise signals, an associated method, and an active noise cancellation headphone using the same. The method is applicable to an audio playback device with multiple ANC filtering units. The method includes: acquiring an anti-noise signal from an ANC filtering unit; generating a decoupled signal by processing the anti-noise signal with the transfer function of a physical channel and operations of other ANC filtering units; performing a signal superposition, wherein an anti-noise signal from another ANC filtering unit is superposed with the decoupled signal; and performing an audio playback based on the superposed signal and an audio signal such that noise is eliminated.
