摘要： The present invention provides a radio transmitter having a digital modulator that further includes logic for continuous amplitude and continuous phase modulation switching in an RF transmitter intended to support both frequency shift keying (FSK) and phase shift keying (PSK) modulation techniques in a smooth and continuous manner that does not violate spectral mask requirements. The invention supports continuous modulation switching both ways, i.e., from FSK to PSK and from PSK to FSK. In operation, the radio transmitter initially operates in a first communication mode, transmitting communication signals to a remote agent according to a first modulation technique at a first data rate and then transitions to the second modulation type at a second data rate without spectral mask violation.

摘要： Designs of devices having digital phase locked loop (DPLL) circuits that include multiple digital feedback loops to generate high frequency clock signals by a digitally controlled oscillator (DCO). A time-to-digital converter (TDC) module is provided in such a DPLL circuit to receive an input reference clock signal and a first feedback clock signal from a first digital feedback loop and produces a digital TDC output indicative of a first phase error caused by a difference in time between the input reference clock signal and the first feedback clock signal. A second digital feedback loop is provided to generate a second digital feedback signal indicative of a second phase error caused by a difference in frequency between a desired clock signal and a generated clock signal generated by the DCO. The first and second digital feedback loops are coupled to the DCO to generate the high frequency clock signals.

摘要： In a radio comprising a transmitter and a receiver, transmission and reception of signals may be controlled based on received signal strength measurements from a signal strength indicator module and transmitted signal strength measurements from the signal strength indicator module. For the transmitted signal strength measurements, the shared signal strength indicator module may measure signal strength of a signal output by a power amplifier. For the received signal strength measurements, the shared signal strength indicator module may measure signal strength of a received signal. A capacitance coupled to an output of the power amplifier may be configured based on a frequency of the signal output by the power amplifier. A gain of the power amplifier may be controlled based on the transmitted signal strength measurements. For the transmitted signal strength measurements, an analog-to-digital converter may process the signal output by the power amplifier.

摘要： A method for processing a plurality of signals may include amplifying an input signal and generating a wideband signal from the amplified input signal. The method may further include bandpass filtering the generated wideband signal to generate a narrowband signal, and adjusting amplification of the input signal based on a narrowband received signal strength indication of the generated narrowband signal, and/or a wideband received signal strength indication of the generated wideband signal. The amplified input signal may be downconverted to generate the wideband signal. The amplified input signal may be downconverted to an intermediate frequency (IF) and/or to a baseband signal to generate the wideband signal. At least one blocker signal may be bandpass filtered from the amplified input signal.

摘要： A method and system for achieving enhanced quality and higher throughput for collocated IEEE 802.11b/g and Bluetooth (BT) devices in coexistent operation are provided. A priority signal may be generated by a BT radio in a coexistence station to disable WLAN transmissions in a WLAN radio when a BT HV3 frame is available for transmission. When the priority signal is asserted, an exponentially growing retransmission backoff mechanism in the WLAN radio may be disabled. Moreover, when the BT radio and the WLAN radio are enabled for coexistence operation, a WLAN fragmentation threshold in the WLAN radio may be modified based on a WLAN modulation rate and the BT HV3 frame duration.

摘要： A Bluetooth low energy (BLE) device receives advertising packets from an advertising BLE device. The BLE device filters the received advertising packets utilizing hardware to search for the advertiser. If the advertiser is not found by the hardware, the packet filtering continues utilizing firmware. Device identity information, comprising non-private and/or private device identities, of preferred BLE devices is partitioned to form a different white list for the hardware, firmware, and host, respectively, to concurrently support privacy and white listing. If the advertiser is found by the hardware, the hardware sends a response to the advertiser following a successful CRC check performed in the hardware. If the advertiser is found by the firmware, the device identity information of the advertiser is inserted in the white list for the hardware. The host may be awakened based on the device configuration and/or attribute type information of the received advertising packets.
