Compensating Unit Interface for Feedback Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bidirectional communication systems face challenges in eliminating undesired feedback when output devices without input devices are physically separated, as existing solutions are cumbersome and expensive.
Innovation Solution
A bidirectional communication system with a first compensating unit and at least one second compensating unit, where the first unit generates compensation data and sends it to the second unit via an interface, allowing for the generation of second compensation data to eliminate feedback, even when devices are physically separate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a central unit is used to handle compensation for all affected subsystems, then compensation for undesired feedback can be achieved, but the system becomes cumbersome and expensive
Solution Approach 1:
The patent divides the compensation function into separate compensating units distributed across different bidirectional communication devices. Each compensating unit handles compensation locally for its assigned output unit, eliminating the need for a centralized compensation system. This segmentation reduces system complexity and cost while maintaining effective feedback compensation.
2Device complexity
If compensation is handled within a single bidirectional communication device, then the system structure is simple, but feedback from physically separated output units cannot be compensated
Solution Approach 1:
The patent creates compensating units that can function independently within their local devices while also receiving compensation data from other compensating units via interfaces. This multi-functionality allows each compensating unit to handle both local feedback compensation and remotely generated feedback compensation, enabling comprehensive coverage without requiring a centralized system.
3Reliability
If multiple compensating units are distributed across separate devices with interfaces for data exchange, then feedback compensation can be achieved for physically separated output units, but the system complexity increases
Solution Approach 1:
The patent uses standardized interfaces as intermediaries between distributed compensating units. These interfaces enable compensation data to be exchanged between physically separated devices without requiring complex direct connections or centralized control. The interface acts as a mediator that simplifies the interaction between distributed compensating units, reducing overall system complexity while enabling comprehensive feedback compensation.

AI summary
A bidirectional communication system includes—a first compensating unit to which a first output unit and a first input unit are assigned that is configured to compensate for undesired feedback from the first output unit in the first input unit with generation of first compensation data and at least one second compensating unit that is configured like the first compensating unit and is physically separate from the first compensating unit. The second compensating unit has a second output unit but no input unit is assigned to it. The first compensating unit and the second compensating unit are connected by interfaces via which the first compensation data generated by the first compensating unit can be sent to the second compensating unit so that second compensation data can be generated in the second compensating unit based on the first compensation data.
