摘要： There is provided a method for hierarchical modulation relating to a first signal, a second signal, and an original constellation having a plurality of symbols in a non-uniform 8 Phase-Shift-Keying (PSK) configuration. Quadrature-Phase-Shift-Keying (QPSK) modulation is used for the first signal and Binary-Phase-Shift-Keying (BPSK) modulation is used for the second signal. The method includes the step of replacing at least some of the plurality of symbols with at least one radial-type QPSK-BPSK constellation.

摘要： A system for controlling configuration settings for mobile data communication devices and services includes a redirection server and a policy generation system. The redirection server detects a triggering event in a host system and in response to the triggering event continuously redirects data items from the host system to a wireless network. Each mobile data communication device receives data items from the wireless network and includes a device configuration stored in a memory location on the mobile data communication device. The device configuration of each mobile data communication device controls one or more functions of the mobile data communication device. The policy generation system receives a policy setting from a user interface and stores the policy setting in a user information record associated with a mobile data communication device. The redirection server detects the policy setting in the user information record and in response to detecting the policy setting transmits the policy setting over the wireless network to the mobile data communication device associated with the user information record. The mobile data communication device automatically modifies the device configuration to include the policy setting. Methods of controlling a configuration setting in mobile data communication devices are also disclosed.

摘要： A receiver comprises a number of fingers, each finger providing symbols associated with a path of a received multipath signal, and a maximal ratio combiner (MRC) that activates to combine the symbols when the symbols are available. In an illustrative embodiment a receiver is a CDMA receiver and comprises a number of fingers, an interface, and an MRC. Each finger provides symbols asociated with a path of a received multipath signal for the various channels conveyed therein, the interface provides an indiction when symbols from the fingers are ready for processing to the MRC, which then activates to combine those symbols from the fingers that are asociated with the same channel. Illustratively, the interface includes a priority encoder for selecting different channels for processing by the MRC. Further, the MRC can be configured to operate with a clock rate that is greater than a chip rate. By selectively activating the MRC, or at least a portion thereof, a reduction in the number of combining circuits can be achieved within the MRC.

摘要： The disclosed embodiments may relate to a method and apparatus for performing a correlation with respect to a received signal. A first correlator may correlate for a real part of a first characteristic of the received signal to produce a first real correlated signal. A second correlator may correlate for an imaginary part of the first characteristic of the received signal to produce a first imaginary correlated signal. A third correlator may correlate for a real part of a second characteristic of the received signal to produce a second real correlated signal. A fourth correlator may correlate for an imaginary part of the second characteristic of the received signal to produce a second imaginary correlated signal. Logic may combine a signal that corresponds to the first real correlated signal, a signal that corresponds to the first imaginary correlated signal, the second real correlated signal and the second imaginary correlated signal to produce a real part of a frequency adjusted signal and an imaginary part of the frequency adjusted signal.

摘要： A method and apparatus for improving performance in communication systems is provided. In one implementation, initial encoded data that has been encoded with a rateless code is received. A quality metric is determined for a communication medium on which the initial encoded data has been received. A modulation scheme used in sending the initial encoded data on the communication medium is identified. An estimate is determined, based on the identified modulation scheme and the determined quality metric, of an amount of mutual information being received per unit of received encoded data. An amount of mutual information being received is determined, based on the determined estimate.

摘要： A method for enabling simultaneous data transmissions in a wireless network includes broadcasting a first signal from a first node, receiving the first signal by a second node, and transmitting a second signal derived from the first signal by the second node. The second signal is received by the first node. A third signal is transmitted from a third node to the first node simultaneous with transmitting the second signal. The first node receives a combination signal which includes the second signal and the third signal. The first node then decodes the third signal from the combination signal using the first signal.
