    Abstract: A wireless communication device for concurrent transmission is described. The wireless communication device includes a first transmitter that sends a first transmit packet on a first frequency. The wireless communication device also includes a second transmitter that sends a second transmit packet on a second frequency that overlaps in time with the first transmit packet. The wireless communication device further includes a processor that coordinates when the first and second transmit packets end such that a first receive packet does not overlap in time with a second receive packet or the second transmit packet. The wireless communication device additionally includes a demodulator that demodulates both the first receive packet in response to the first transmit packet and the second receive packet in response to the second transmit packet.

    Abstract: A method for communications is described. The method includes determining a symbol timing drift elimination amount for a received signal. The method further includes eliminating part of the symbol timing drift by adjusting a reference clock for the modem. Determining the symbol timing drift elimination amount may be based on at least one of a symbol timing drift estimate, a symbol timing error, a packet acquisition indicator, a packet validity indicator, demodulated bits or a carrier presence indicator.

    Abstract: Hardware interrupt functionality associated with a disable pin may be used to place a near-field communication (NFC) device into various operational modes. For example, various intermediate voltage windows may be defined within an I/O voltage domain and a resistive divider running off an I/O rail may generate multiple reference voltages within the I/O voltage domain. In one embodiment, different comparators may compare voltage on the disable pin to the reference voltages generated with the resistive divider to determine whether the voltage on the disable pin falls within one of the intermediate voltage windows. As such, if a particular comparator determines that the voltage on the disable pin falls within one of the intermediate voltage windows, a control signal may be generated to transition the NFC device into a corresponding operational mode.
