摘要： Aspects of a method and system for compensating for distortion in a transmitter by utilizing a digital predistortion scheme with a 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.

摘要： Methods and systems for enabling coexistence of multiple potentially interfering wireless components in a device are provided. A device may include a wireless module using a proprietary protocol and one or more modules using standardized protocols. The device further includes a coexistence arbitration module configured to arbitrate access to a shared communication medium among the wireless modules based on assertion of medium access requests by the modules and the associated priority of the asserted medium access requests. When multiple medium access requests have the same priority, precedence for access to the shared medium is determined based on additional criteria. The coexistence arbitration module may be a separate module or may be integrated into another module or distributed among the modules. The device may include a host processor for altering transmission characteristics of a module to increase the likelihood that another module can receive data within a reasonable time period.

摘要： Wi-Fi proximity considerations within single user, multiple user, multiple access, and/or MIMO wireless communications. Communications between a 1st wireless communication device (WDEV) (e.g., mobile) and a 2nd WDEV (e.g., terminal) are effectuated using wireless local area network (WLAN) based communications. Such communications may be adaptively performed based on at least one of proximity of the 1st WDEV to the 2nd WDEV and a predetermined movement of the 1st WDEV with respect to the 2nd WDEV or an object associated with the 2nd WDEV. For example, such a transaction may be effectuated between the 1st WDEV and the 2nd WDEV based on at least one (e.g., any one, any combination, any sub-combination, etc.) of received signal strength indicator (RSSI), angle of arrival (AoA), and time of flight (ToF) associated with at least one communication between the 1st WDEV and the 2nd WDEV.
