Abstract: Dynamically splitting a job in wireless system between a processor other remote devices may involve evaluating a job that a wireless mobile communication (WMC) device may be requested to perform. The job may be made of one or more tasks. The WMC device may evaluate by determining the availability of at least one local hardware resource of the wireless mobile communication device in processing the requested job. The WMC device may apportion one or more tasks making up the requested job between the wireless mobile communication device and a remote device. The apportioning may be based on the availability of the at least one local hardware resource.

Abstract: Systems, apparatuses and methods are disclosed for apportioning tasks among devices. One such method is performed in handheld wireless communication device (HWCD). The method includes discovering available resources in a network and dynamically assessing cost functions for performing a task on the HWCD and on each of the discovered resources. Each of the respective cost functions is based on performance factors associated with the HWCD or with one of the devices. Based on change in the cost functions, the task is apportioned for local execution by the HWCD or remote execution by the available resources.

Abstract: Aspects of a method and system for estimating and compensating for non-linear distortion in a transmitter using calibration are presented. Aspects of the system may include one more circuits that may enable estimation, within a single IC device, of distortion in output signals generated by a transmitter circuit. The circuitry may enable compensation of the estimated distortion by predistorting subsequent input signals. The transmitter circuit may generate subsequent output signals based on the predistorted subsequent input signals.

Abstract: A communication device, such as a smart phone, includes transmit/receive logic to cancel an interfering signal component. The interfering signal component may originate from a communication interface on the device itself. For example, transmissions from the communication interface may interfere with received signals at other communication interfaces on the device. Transmit/receive logic on others of the communication interfaces may use known characteristics of the interfering signal component to cancel the interfering signal component.

Abstract: 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.
