摘要： Provided is a quadrature demodulator capable of appropriately correct an amplitude error and a quadrature error even with respect to a pulse-modulated signal. In the quadrature demodulator 100, in order to compensate an amplitude error and a quadrature error, the phase adjuster 112 is provided in the local oscillation unit 110, and the quadrature detection error detector 131 and the quadrature detection error compensator 132 are provided in the signal processing unit 130. The quadrature detection unit 120 outputs two sets of I and Q-components of an RF signal using two LO signals that have been phase-shifted by the phase adjuster 112. In the quadrature detection error detector 131, an amplitude error and a quadrature error are calculated using the two sets of I and Q-components. The quadrature detection error compensator 132 compensates a received signal using the amplitude error and the quadrature error.

摘要： A control system (16) is provided. The control system includes a radio frequency (RF) transmitter-receiver module (26) configured to transmit and receive first RF signals (30) within a first RF range (104), the RF transmitter-receiver module including at least one RF transmitter-receiver (42), an RF receiver module (24) configured to receive second RF signals (22) within a second RF range (102) that at least partially overlaps the first RF range, the RF receiver module including at least one RF receiver (40), and a processor (28) coupled in communication with the RF transmitter-receiver module and the RF receiver module. The processor is configured to engage (302) in a first communication session (402) with a remote RF device (14) using the RF transmitter-receiver module to transmit a first outgoing message within the first RF signals and detect (304) a second communication session (406) within the second RF signals using the RF receiver module, the second RF signals transmitted by a system RF device (12) and including an incoming message encoded therein. The processor is further configured to, when the second communication session is detected, interrupt (306) the first communication session for a time period (408), receive (308) the second RF signals during the time period using the RF receiver module, and after the time period expires, resume (314) the first communication session.

摘要： A scheduling technique is described for discontinuous transmission and reception. The scheduling technique may be implemented in a mobile communication device with multiple SIMs. The scheduling technique facilitates enhanced communication capability for the mobile communication device. In one implementation, the scheduling technique helps avoid substantial overlap between discontinuous receive cycles of the SIMs, for example by renegotiating a discontinuous transmit / receive offset if too much overlap exists. The renegotiation process may be incorporated into a future industry standard communication protocol (e.g., 3GPP release 11 or later), or may be implemented as an extension to an existing communication protocol.

摘要： A method of operating a radio-frequency (RF) circuitry and a signal-processing circuitry in a mobile telephone apparatus includes at least partially disabling the signal-processing circuitry while transmitting or receiving signals. In one example, a processor is efficiently disabled by generating and servicing an interrupt of relatively high priority. One advantage of this example is that preexisting, legacy code can be maintained, while still achieving the desired objectives. The processor can be enabled by generating and servicing a second high priority interrupt.
