Solution Overview
Problem
Existing transceiver synchronization systems face challenges in accurately determining distances between transceivers, particularly in non-GNSS positioning systems, and require improved measurement accuracy.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If transceivers use standard synchronization methods, then the system can operate, but distance measurement accuracy is insufficient
Solution Approach 1:
The patent segments the synchronization process into multiple independent measurement phases (first wideband signal transmission, second wideband signal transmission with offsets) and multiple transceiver groups (first plurality and second plurality). This segmentation allows each phase to contribute specifically to different aspects of synchronization and distance measurement, improving overall accuracy while maintaining system reliability through redundant measurement paths.
Solution Approach 2:
The patent applies parameter changes by introducing frequency offsets and time delays (second time delays) as modifying parameters for the second wideband signals. These parameter changes enable the system to measure not only distance but also synchronization accuracy and signal propagation characteristics, thereby improving distance measurement accuracy without compromising synchronization reliability.
2Measurement precision
If multiple wideband signals are transmitted with offsets, then distance measurement accuracy improves, but system complexity increases
Solution Approach 1:
The patent implements multi-functionality by designing transceivers that can both transmit and receive wideband signals with different offsets, and by having signal processing units that can generate, transmit, and analyze multiple signal types. This universal design improves distance measurement accuracy through multiple measurement paths while managing complexity by reusing the same hardware components for multiple functions.
Solution Approach 2:
The patent applies preliminary action by having transceivers pre-configure frequency offsets and time delays before signal transmission. The signal processing units prepare the wideband signals with predetermined modifications, and transceivers are pre-synchronized to their respective roles. This preliminary configuration improves measurement accuracy by ensuring proper signal conditions are established before measurement, while managing complexity through automated configuration procedures.

AI summary
A system for synchronizing transceivers which includes a first and second plurality of transceivers. The first plurality of transceivers are arranged at fixed positions with respect to each other. One of the first plurality of transceivers is configured to transmit a first wideband signal. The second plurality of transceivers are arranged at fixed positions with respect to each other. Each of the second plurality of transceivers is configured to receive the first wideband signal and to generate a respective one of second wideband signals based on the respectively received first wideband signal modified by a respective one of offsets which differ from each other, and to transmit the respective one of second wideband signals. The one of the first plurality of transceivers is configured to receive the second wideband signals which form the basis for synchronizing one of the first plurality of transceivers with the second plurality of transceivers.
