Adaptive RF saturation detection in a wireless device implementing multiple wireless protocols

摘要

System and method for detecting radio frequency (RF) saturation in a wireless device configured to simultaneously receive first signals according to a first wireless protocol and second signals according to a second wireless protocol. Signals having components of both the first and second signals may be received at a shared gain element. A level of saturation of the shared gain element may be determined. A current definition of a saturation event may be determined. A gain adjustment value may be determined based on the level of saturation and the current definition of a saturation event. A gain value of the shared gain element may be adjusted by the determined gain adjustment value.

主权项

1. A wireless device, comprising:
an antenna for receiving wireless signals; first wireless protocol circuitry coupled to the antenna and configured to receive first signals from the antenna, wherein the first wireless protocol circuitry is configured to process the first signals according to the first wireless protocol; second wireless protocol circuitry coupled to the antenna and configured to receive second signals from the antenna, wherein the second wireless protocol circuitry is configured to process the second signals according to the second wireless protocol; a first shared gain element utilized by the first wireless protocol circuitry and the second wireless protocol circuitry; and logic configured to detect saturation events for received signals, wherein the logic is configured to adjust a gain value of the first shared gain element based at least in part on a detected saturation event; wherein the logic is configured to dynamically adjust a definition of a saturation event based at least in part on a priority of one or more of the first signals or the second signals.
