    Abstract: A mobile device may be configured to perform concurrent Satellite Positioning System (SPS) operation and wireless communications when uplink signals transmitted by the mobile device interferes with the reception of SPS signals in one or more frequency bands. The mobile device may determine if the SPS receiver has already acquired SPS signals and is in a tracking state. If the SPS receiver is not in a tracking state, an SPS acquisition procedure is initiated before the wireless communication session is initiated. The SPS acquisition procedure is performed until the SPS receiver reaches a tracking state, or until a timeout is reached. Once the SPS receiver is in a tracking state, the wireless communication session may be initiated, during which the SPS receiver is controlled, e.g., to perform signal blanking, measurement exclusion, or disable SPS reception, to mitigate interference with SPS signals.

    Abstract: Systems and methods relate to extracting a small sideband signal from a received signal having the small sideband with a small frequency offset from a large carrier signal. The received signal is down-converted from a transmission frequency and the large carrier signal is filtered out. A threshold comparator is configured to compare the resultant sideband signal with a first signal threshold and a second signal threshold. If the sideband signal exceeds the first signal threshold in a first direction, the sideband signal is restored to a data signal with a first data value. The restored data signal is retained at the first data value until the sideband signal exceeds a second signal threshold in a second direction, at which time the sideband signal is restored to the data signal with a second data value.

    Abstract translation: 系统和方法涉及从具有小载波信号的小频率偏移的小边带的接收信号中提取小边带信号。 接收到的信号从传输频率被下变频，并且大载波信号被滤除。 阈值比较器被配置为将所得到的边带信号与第一信号阈值和第二信号阈值进行比较。 如果边带信号在第一方向上超过第一信号阈值，则边带信号被恢复为具有第一数据值的数据信号。 恢复的数据信号保持在第一数据值，直到边带信号在第二方向上超过第二信号阈值，此时边带信号以第二数据值恢复到数据信号。

    Abstract: A positioning signal processing method includes: receiving, wirelessly at an apparatus, a first positioning signal in a first frequency range; receiving, wirelessly at the apparatus, a second positioning signal in a second frequency range; converting the first positioning signal by a first analog-to-digital converter (ADC) of the apparatus to produce a first digital signal at a first sampling rate that is based on a clock signal; and converting the second positioning signal by a second ADC of the apparatus to produce a second digital signal at a second sampling rate that is based on the clock signal and that is different from, and related to, the first sampling rate.

    Abstract: An apparatus includes: a transceiver configured to receive a satellite signal and to transmit one or more outbound signals; a memory; and a processor, communicatively coupled to the transceiver and the memory, configured to: transmit, via the transceiver, the one or more outbound signals; blank a first portion of the satellite signal spanning a first frequency set that includes at least a portion of an interference signal corresponding to transmission of the one or more outbound signals by the transceiver; and process a second portion of the satellite signal spanning a second frequency set that includes no frequencies of the interference signal; wherein the first frequency set and the second frequency set are different frequency portions of a same time portion of the satellite signal.
