DSL Vectoring Cross-Connect Externalizing Computation

The patent extracts the complex vectoring computation functions from the DSL transceiver devices and relocates them to external servers. The DSL transceivers only need to exchange raw signal data with the server, which then performs the computationally intensive crosstalk mitigation calculations. This extraction resolves the contradiction by maintaining performance improvement while eliminating the complexity burden from the customer premises equipment.

The patent introduces an intermediary server that acts as a mediator between multiple DSL transceivers. This server coordinates the vectoring operations by collecting signal data from all transceivers, performing joint signal processing to mitigate crosstalk, and distributing the processed signals back to the appropriate transceivers. The intermediary handles the computational complexity centrally, allowing individual transceivers to benefit from crosstalk mitigation without implementing the complex algorithms themselves.

The patent merges multiple vectoring computations into a single centralized processing operation performed by the server. Instead of each DSL transceiver independently performing complex vectoring calculations (which would multiply energy consumption across multiple devices), the system combines all vectoring operations into one centralized computation that serves all transceivers simultaneously. This merging reduces total energy consumption while maintaining performance benefits.

The patent uses a copy-based approach where the server computes vectoring coefficients once based on aggregate signal data from all transceivers, then distributes these coefficients to all transceivers. This avoids redundant computation at each transceiver and reduces overall energy consumption while maintaining the performance improvements from vectoring.
