Periodic Wave Data Signaling With Simplified Bit Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional signal transmission techniques require complex duty ratio detection, increasing the workload and cost for the receiving end, as they use waves with the same period to distinguish bit 1 and bit 0 based on duty ratios.
Innovation Solution
Transmitting data bit 1 and data bit 0 using periodic waves with different periods (T1 and T2), where T1 is unequal to T2, allowing the receiving end to determine the bit sequence based on the period of the periodic wave, thereby simplifying the detection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional signal transmission technique uses waves with the same period to distinguish bit 1 and bit 0 by duty ratios, then data transmission can be achieved, but the detection process becomes complicated and increases workload and cost for the receiving end
Solution Approach 1:
The patent changes the transmission parameter from duty ratio (within same period) to period length itself. By using periodic waves with different periods T1 and T2 to represent bit 1 and bit 0 respectively, the receiving end only needs to detect the period length rather than performing complex duty ratio measurements, thereby simplifying the receiving end's processing complexity while maintaining reliable data transmission
2Loss of information
If conventional signal transmission technique uses duty ratio detection to distinguish bits, then data can be transmitted, but the detection process is complicated and increases cost
Solution Approach 1:
The patent transforms the detection task from measuring duty ratio (which requires complex timing and comparison circuits) to measuring period length (which can be achieved through simpler frequency detection methods). By encoding bits as different period lengths T1 and T2, the receiving end can use straightforward period detection to recover data, significantly reducing detection difficulty while preserving data accuracy
