Receiver Power Control for Blocker-Resistant Signal Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems fail to adapt power consumption based on varying signal conditions, leading to inefficient power usage and performance trade-offs, especially when receiving signals with strong undesired blockers or changing channel conditions.
Innovation Solution
A communication receiver system that quantitatively estimates receive signal factors such as channel quality, signal characteristics, and error rates, and adjusts performance parameters like RF dynamic range, phase noise, and channel decoder performance to minimize power consumption, using a receiver front end circuit and signal strength detectors to implement these adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the receiver maintains high performance settings to ensure reliable signal reception, then reception reliability is improved, but power consumption increases
Solution Approach 1:
The receiver dynamically adjusts its performance parameters (such as signal processing complexity, decoding effort, and filtering strength) based on real-time channel conditions. When channel quality is good, the receiver operates in a lower-power mode with reduced processing. When channel quality degrades, the receiver automatically increases processing performance to maintain reception reliability, thus resolving the contradiction between reliability and power consumption.
Solution Approach 2:
The system changes operational parameters (processing depth, algorithm complexity, component activation levels) according to channel conditions. By monitoring signal quality metrics and adapting performance parameters accordingly, the receiver optimizes the trade-off between maintaining reliable reception and minimizing power consumption in varying environmental conditions.
2Object-affected harmful factors
If the receiver increases performance parameters to handle strong blockers, then blocking resistance is improved, but power consumption increases
Solution Approach 1:
The receiver applies different processing strategies to different signal components. When blockers are detected, the system selectively enhances processing only for the desired signal path while maintaining or reducing processing for other paths. This localized enhancement provides blocker resistance only where needed, avoiding unnecessary power consumption in other receiver functions.
Solution Approach 2:
The receiver dynamically switches between different processing modes based on blocker detection. In normal conditions, standard processing is used. When strong blockers are detected, the system activates enhanced interference rejection algorithms specifically for affected frequency ranges or time periods, then returns to normal operation, optimizing power consumption while providing blocker resistance when required.
3Reliability
If the receiver uses higher performance settings for poor channel conditions, then reception quality is improved, but power consumption increases
Solution Approach 1:
The receiver continuously monitors channel quality metrics (signal-to-noise ratio, bit error rate, packet error rate) and uses this feedback to adjust its performance parameters. When channel conditions are poor, the feedback loop triggers increased processing performance to maintain reception quality. When conditions improve, the system reduces performance settings, thereby optimizing power consumption while maintaining quality through closed-loop control.
Solution Approach 2:
The system transitions between different operational states (low-power mode, medium-power mode, high-power mode) based on real-time channel assessments. This dynamic adaptation allows the receiver to match its performance and power consumption to the actual reception needs, avoiding unnecessary power consumption in good conditions while ensuring quality in poor conditions.

AI summary
Methods and systems for providing reduced bandwidth acquisition latency may comprise communicating a reservation request for bandwidth allocation for devices operating under a wired network protocol, where the reservation request may be sent by wired network devices via a wireless network protocol over a wireless network. Bandwidth may be allocated in the wired network for the requesting devices by a network controller. Data may be communicated with the requesting devices via the wired network. The wired network communication protocol may comprise a multimedia over cable alliance (MoCA) standard. The wireless protocol may comprise an IEEE 802.11x standard, a Bluetooth standard, and/or any non-public network protocol. The communication of the reservation request via the wireless protocol may decrease a latency of the wired network. A medium access plan (MAP) may be generated by the network controller based on the reservation request and may comprise a bandwidth allocation for the requesting devices.
