Interference Module Predicts Wireless Signal Disturbance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication devices face significant interference from coexisting transceivers, such as WiFi and Bluetooth, which current interference estimation and cancellation schemes fail to adequately mitigate, leading to corruption of baseband receiver signal processing functions like automatic gain control, synchronization, and channel estimation.
Innovation Solution
A wireless communication device equipped with an interference module that predicts upcoming interference and provides information to receiver components to adjust their processing parameters, allowing for the localization and constrainment of transient effects caused by interference, such as aligning the transmission of interfering signals with selected portions of concurrently received or transmitted signals.

Engineering Contradiction Analysis
1Object-affected harmful factors
If interference cancellation schemes are used to mitigate interference from coexisting transceivers, then interference reduction is achieved, but the schemes fail to adequately protect baseband receiver signal processing functions
Solution Approach 1:
The system performs preliminary action by predicting upcoming interference from coexisting transceivers before it occurs. The interference predictor analyzes patterns from the coexisting transceiver to forecast future interference events, allowing the receiver to proactively adjust its processing functions before interference corruption can occur, rather than attempting cancellation after interference has already degraded the signal
Solution Approach 2:
The system applies preliminary anti-action by having the receiver component adjust its processing parameters in advance of predicted interference events. The receiver suspends or modifies vulnerable signal processing functions before the predicted interference occurs, creating a protective effect that prevents interference from corrupting the baseband processing, rather than attempting to cancel interference after it has already caused harm
2Reliability
If receiver functions are continuously adjusted to mitigate interference, then signal processing reliability improves, but processing delays and loss of useful signal data occur
Solution Approach 1:
The interference predictor enables preliminary action by forecasting interference events in advance, allowing the receiver to make brief, targeted adjustments only when needed. This predictive approach avoids continuous adjustment of receiver functions, maintaining normal processing during non-interference periods while providing protective adjustments only during predicted interference events, thus minimizing processing delays
Solution Approach 2:
The system applies partial action by adjusting only the specific receiver functions that are vulnerable to interference during predicted interference events, rather than continuously adjusting all processing functions. The receiver selectively suspends or modifies only the necessary processing steps during brief interference windows, maintaining full processing capability during normal conditions, thereby reducing overall processing delays while still protecting against interference
Data Source
AI summary
A system including an interference module. The interference module is configured to determine, based on first data to be transmitted from a wireless communication device, information about interference predicted to be caused by the first data being transmitted, and provide, to a receiver of the wireless communication device, the information about the predicted interference. A component of the receiver of the wireless communication device is configured to receive, from the interference module, the information about the predicted interference, and adjust, for a duration of the predicted interference, a function performed by the component of the receiver. The function performed by the component of the receiver is related to processing a signal received by the receiver of the wireless communication device.
