RF Receiver Overlap for Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face interference issues due to the lack of hard wiring, leading to increased system latency and potential signal blockages that can disrupt communication between electronic devices.
Innovation Solution
A radio frequency system with multiple receivers operating on different channels, utilizing a 50% reception overlap period and equal dwell times to ensure continuous signal reception, even if one or more channels are blocked, thereby reducing system latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple receivers operate on different channels without overlap, then device complexity is reduced, but system latency increases and reliability decreases when channels are blocked
Solution Approach 1:
The patent applies preliminary action by pre-configuring receivers to operate on different channels with predetermined overlap periods. This advance planning ensures that when one channel is blocked, another receiver is already positioned to immediately take over, reducing latency without requiring complex real-time coordination.
Solution Approach 2:
The patent segments the communication system into multiple receivers operating on different channels simultaneously. Each receiver handles a specific channel segment, and the overlap period creates a buffer zone that ensures continuous coverage. This segmentation allows parallel operation while maintaining reliability through the overlapping time periods.
2Loss of time
If receivers operate with 50% reception overlap period, then system latency is reduced and channel blockage resistance improves, but energy consumption increases
Solution Approach 1:
The patent implements periodic action through the 50% overlap period configuration, where receivers operate in structured time cycles with predetermined overlap. This periodic pattern ensures that during the overlap period, receivers are active to catch potential signals, but outside this period, they can enter lower-power states, balancing latency reduction with energy management.
3Productivity
If receivers use equal dwell time on each channel, then fairness and load balancing improve, but adaptability to varying signal conditions decreases
Solution Approach 1:
The patent applies parameter changes by allowing receivers to dynamically adjust their dwell time and overlap period parameters based on detected signal conditions. When signal quality varies on different channels, the system can modify the time allocation parameters to optimize performance, balancing fair resource distribution with adaptability to changing environments.

AI summary
A method of operating a communicator includes operating a first receiver of a plurality of receivers on a first channel of a series of channels. A second receiver of the plurality of receivers is operated on a second channel of the series of channels. A third receiver of the plurality of receivers is operated on a third channel of the series of channels. The second receiver that operates on the second channel includes a reception overlap period of about 25% to about 75% with the first receiver that operates on the first channel and a reception overlap period of about 25% to about 75% with the third receiver that operates on the third channel.
