Aspects of a method and system for compensating for estimated distortion in a transmitter by utilizing a digital predistortion scheme with a quadrature feedback mixer configuration are presented. Aspects of the system may include an RF transmitter that enables generation of an RF output signal in response to one or more generated input signals. One or more feedback signals may be generated by performing frequency downconversion on the RF output signal within a corresponding one or more feedback mixer circuits. The generated one or more feedback signals may be inserted at a corresponding one or more insertion points in an RF receiver. Each insertion point may be between a receiver mixer circuit and corresponding circuits that generate a baseband signal based on the corresponding one of the feedback signals.

A system and method providing low-power operation in a multimode communication device. Various aspects of the present invention may, for example, include at least one radio module that is adapted to communicate in a plurality of communication modes. The at least one radio module may also be adapted to operate in at least a first power-save mode. At least one module may, for example, be adapted to analyze at least one non-informational aspect of a signal (e.g., a received radio signal) to determine whether a first communication network corresponding to a first communication mode of the plurality of communication modes might be available. The at least one module may then, for example, be adapted to determine, based at least in part on the determined availability of the first communication network, whether to operate the at least one radio module in a respective mode other than the first power-save mode.

A handheld wireless communication device (HWCD) establishes an ad hoc network comprising interconnected networks for a user. The HWCD gains access to content on a first device and controls communication of the content from the first device via the HWCD to a second device. The HWCD enables the second device to consume the content. The content may be streamed from the first device via the HWCD to the second device. The first device is a service provider network device or other network device. The access may be authenticated and/or secure. Secure access to the content is extended from the first device to the second device. The ad hoc network is configured and/or reconfigured until communication is complete. The HWCD comprises multiple wireless interfaces. The ad hoc network comprises a PAN, WLAN, WAN and/or cellular network. The HWCD may hand-off among base stations during communication of the content.

Methods and systems for a persistent request generated by a wireless device, executed remotely and output to configurable local resources are disclosed and may include generating via a handheld wireless communication device (HWCD) a persistent request for a user that may be communicated to remote devices for execution and storage of results. The stored results may be received from local resources local which may be configured by the remote devices based on user preferences to deliver the stored results to the user. The stored results may be received by the user via the HWCD or another wireless communication device, and the identity of the user may be authenticated prior to receiving the stored results. The remote devices may discover the local resources based on the detection of the user logging into the network. User preferences may be stored in networked devices or may be stored in the HWCD.
摘要:
A system and method providing concurrent multimode communication through multimode signal multiplexing. Various aspects of the present invention may comprise, during a first time period, transmitting a first portion of a first communication in a first communication mode in a serial wireless transmission stream. During a second time period after the first time period, a first portion of a second communication may be transmitted in a second communication mode in the serial wireless transmission stream. Also, during a third time period after the second time period, a second portion of the first communication may be transmitted in the first communication mode in the serial wireless transmission stream. In an exemplary scenario, prior to communicating various communications, transmission time may be allocated between the first and second communication modes. In another exemplary scenario, transmission may be switched between a plurality of communication modes in response to detected communication conditions.
