Vectored Group Connection Initialization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vectoring data transmission systems, adding a new communication connection to an existing vectored group often disrupts data throughput due to crosstalk, which existing methods struggle to minimize effectively during initialization and ongoing communication.
Innovation Solution
A method involving two phases of vector training and initialization: first, adapting vectoring to reduce crosstalk from the new connection to existing connections, followed by partial initialization, and second, adapting vectoring to reduce crosstalk from existing connections to the new connection, allowing for synchronized data transmission without disrupting existing data flows.

Engineering Contradiction Analysis
1Productivity
If a new communication connection is added to the vectored group, then the system capacity and number of active users are improved, but crosstalk interference increases and data throughput of existing connections deteriorates
Solution Approach 1:
The patent applies preliminary action by performing a first vector training phase before the new connection fully initializes. During this phase, the system pre-adapts the vectoring parameters to account for the upcoming crosstalk from the new connection, thereby preparing the system in advance to minimize interference when the connection becomes active.
Solution Approach 2:
The patent implements feedback through iterative vector training phases. The system measures crosstalk effects during initialization and ongoing communication, then continuously adjusts vectoring parameters based on this feedback. The second vector training phase refines the adaptation based on actual performance data, creating a closed-loop control system that minimizes crosstalk dynamically.
2Object-generated harmful factors
If vectoring is adapted to reduce crosstalk from the new connection to existing connections, then crosstalk interference is reduced, but the initialization process becomes more complex and time-consuming
Solution Approach 1:
The patent segments the initialization and adaptation process into distinct phases: a first vector training phase focused on reducing crosstalk from the new connection to existing connections, followed by partial initialization, then a second vector training phase for reducing crosstalk in the opposite direction. This segmentation allows each phase to be optimized independently and managed systematically.
Solution Approach 2:
The patent applies dynamics by making the vectoring parameters adaptive rather than static. The system dynamically adjusts vectoring coefficients during the different training phases based on measured crosstalk conditions. This dynamic adaptation allows the system to respond to changing interference patterns while maintaining optimized performance throughout the initialization process.
3Productivity
If vector training is performed to minimize crosstalk, then data throughput is improved, but the time required for initialization and connection setup increases
Solution Approach 1:
The patent performs preliminary vector training during the initialization phase to establish optimized vectoring parameters before full data transmission begins. This preliminary adaptation ensures that when data transmission starts, the crosstalk is already minimized, avoiding the need for disruptive retraining later and reducing overall setup time.
Solution Approach 2:
The patent maintains continuity of useful action by overlapping vector training with partial initialization activities. Rather than completing all training before any data transmission, the system performs vector training phases while allowing partial initialization to proceed, ensuring that useful data transmission activities continue without complete interruption while still achieving optimized crosstalk reduction.
