Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If duplicated transmission paths are used to detect interference, then interference detection capability is improved, but overhead increases and transmission efficiency deteriorates
Solution Approach 1:
The patent creates a virtual copy of the transmission path by generating imaginary received signals through signal processing rather than using physical duplicated paths. The interference detection unit compares the actual received signal with these generated imaginary signals to detect interference, achieving reliable detection without the overhead of true path duplication
Solution Approach 2:
The patent introduces an intermediary signal processing mechanism that generates imaginary received signals as mediators between the actual received signal and the interference detection process. This intermediary approach allows interference detection without requiring direct duplication of the physical transmission path
2Reliability
If duplicated transmission paths are used to detect interference, then interference detection capability is improved, but system complexity increases
Solution Approach 1:
Instead of duplicating physical transmission path infrastructure, the patent creates virtual copies through signal processing operations. The interference detection is achieved by comparing actual signals with imaginarily generated signals, avoiding the complexity of managing multiple physical paths while maintaining detection capability
Solution Approach 2:
The patent replaces the mechanical/physical system of duplicated transmission paths with a signal processing-based virtual system. By using mathematical operations to generate imaginary received signals, the system eliminates the need for complex physical infrastructure while achieving the same interference detection function

AI summary
A receiving device of an embodiment has a receiver, a demultiplexer, and an interference detector. The receiver receives a multiplexed signal. The demultiplexer demultiplexes the multiplexed signal into a plurality of signals. The interference detector, with referring to bit transitions of the plurality of signals in a predetermined time period, detects interference in the multiplexed signal.
