Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems struggle to accurately localize and mitigate message faults without resorting to costly retransmissions or bulky error-correction codes, especially in high-density urban and industrial settings.
Innovation Solution
A wireless receiver identifies and corrects message faults by analyzing waveform signals for amplitude and phase fluctuations, polarization irregularities, and frequency offsets, using modulation error thresholds and AI models to determine faulted message elements and correct them in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If error-correction codes are embedded in the message, then reliability is improved, but device complexity and resource consumption increase
Solution Approach 1:
The patent extracts fault localization capability from traditional error-correction codes. Instead of using bulky FEC codes that treat all errors uniformly, the system extracts only the necessary information (waveform signatures) to identify and locate faults, separating the detection function from the correction function. This allows reliability improvement without the full complexity burden of traditional error-correction codes.
Solution Approach 2:
The patent introduces waveform signature analysis as an intermediary between signal reception and fault correction. This intermediary layer analyzes the physical waveform characteristics to identify faults, providing a bridge that enables localized correction without requiring the full machinery of traditional error-correction codes. The waveform signature acts as a mediator that provides fault information with minimal overhead.
2Reliability
If retransmission is used to correct faults, then reliability is improved, but loss of time and power increase
Solution Approach 1:
The patent applies preliminary action by analyzing waveform signatures in real-time during the initial message reception to identify and locate faults before retransmission becomes necessary. The system performs fault detection and localization as a preliminary step, enabling the receiving device to correct errors independently without waiting for retransmission instructions. This preliminary waveform analysis prevents the need for time-consuming retransmission cycles.
Solution Approach 2:
The patent enables self-service by equipping the receiving device with the capability to autonomously detect, locate, and correct faults using waveform signature analysis. Instead of passively receiving corrected messages through retransmission, the system actively performs fault mitigation itself, reducing dependency on time-consuming retransmission protocols and saving both time and power resources.
3Ease of operation
If traditional fault detection methods are used, then ease of operation is maintained, but measurement precision and fault localization capability deteriorate
Solution Approach 1:
The patent applies local quality by analyzing waveform signatures at specific localized positions within the message to identify and locate faults. Instead of treating the entire message uniformly, the system examines individual segments or regions of the waveform, providing precise localization of faulted elements. This localized analysis maintains operational simplicity while dramatically improving measurement precision and fault localization capability.

AI summary
Message faulting is the leading cause of poor reception. Currently, most faulting in 5G and 6G requires either transmission of bulky FEC bits, or retransmission of the message, at substantial delay and cost. This paper shows how the receiver can internally (autonomously) correct the message faults by scanning the digitized waveform signals, to detect characteristic fault signatures that clearly identify the likely faulted subcarriers. With that information, and the CRC or other appended code, and optionally an AI assist, the receiver can correct the message in a fraction of the time required for a retransmission. The message is corrected instantly, with zero background generation, zero bandwidth consumption, and zero cost. Autonomous fault mitigation in the receiver is the most efficient way to improve user reception.
