摘要： A near-field communication circuit (100), such as a radio frequency identification circuit, includes a communication coil (104) and a communication circuit (108) configured to transmit data (109) through the communication coil (104). When the communication circuit (108) is in an idle mode, probing circuitry (124) is configured to detect the presence of a magnetically conductive object within close proximity of a communication coil (104). In one embodiment, a control circuit (110) selectively couples a capacitance (125) in parallel with the communication coil (104). The control circuit (110) then applies a probing signal (116) to the communication coil (104). A comparator (118) monitors a secondary parameter of the communication coil (104), such as inductance or impedance. When a magnetically conductive object is detected, the communication circuit (108) transitions to a communication state and attempts to communicate with the object.

摘要： A method to reduce crossmodulation in a multimode radio communication device with a transmitter, a receiver, and a second receiver (400) that operates in a receiver channel bandwidth (402) includes a step of measuring a first signal strength in the receiver channel bandwidth (404), a second signal strength outside of the receiver channel bandwidth (406), and a power level of the transmitter. A next step (408) includes determining a signal-to-crossmodulation interference ratio (SCMIR). A next step (410) includes calculating a SCMIR threshold. A next step (412) includes comparing the ratio to the threshold. A next step (416,420) includes increasing the linearity of the receiver if the ratio is less than the threshold.

摘要： A narrowband interference cancellation system, method and digital signal processor is disclosed that removes narrowband interference in wide band communication systems. The system includes a narrowband processing component, wideband processing component, soft metric generator and at least one filter. The system is configured to receive a signal, identify one or more narrowband interferers in the received signal and filter out identified narrowband interferers. The narrowband processing component includes a filter bank configured to separate the received signal into a predetermined number of channel bands and identify a band with interference. The wide band processing component provides an average level for an unfiltered version of the received signal. The soft decision metric generator produces metrics based on predetermined thresholds. The filters receive coefficients that are determined using outputs from the soft decision metric generator that are first averaged using long term integrators and then stored in lookup tables.

The bus interface is adapted to convert the communication signals between communication signals having distinct signal levels, and communication signals having compatible signal levels. Where in at least some instances, the conveyed communication signals are converted from communication signals having distinct signal levels to communication signals having compatible signal levels, and then back to communication signals having distinct signal levels, after the communication signals having compatible signal levels are transmitted and received via one or more associated communication paths.
