Periodic Wave Data Transmission Method for Reducing Receiver Complexity
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
The method involves transmitting data bits 1 and 0 using periodic waves with different periods (T1 and T2), allowing the receiving end to determine the bit sequence based on the period of the wave, thereby simplifying the detection process and reducing processing complexity and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If duty ratio detection is used to distinguish bit 1 and bit 0, then data transmission can be achieved, but the processing complexity and cost for the receiving end increase
Solution Approach 1:
The patent changes the parameter used for data encoding from duty ratio (within same period) to period length itself. By using different periods T1 and T2 for bits 1 and 0 respectively, the receiving end can directly determine bit values by measuring period length rather than calculating duty ratios, significantly simplifying the detection process while maintaining transmission reliability
Solution Approach 2:
The patent extracts the period parameter from the wave signal for data encoding purposes. Instead of encoding data within a fixed period using duty ratios, the period itself becomes the carrier of information. This extraction allows the receiving end to directly measure and interpret the period length to determine bit values, eliminating the need for complex duty ratio calculation circuits
2Loss of information
If duty ratio detection is implemented, then bit 1 and bit 0 can be distinguished, but the workload and cost for the signal receiving end increase
Solution Approach 1:
The patent changes the encoding parameter from duty ratio to period length. This transformation makes the receiving end operation simpler because it only needs to measure the period length of the incoming wave rather than perform complex duty ratio calculations. The bit distinction capability is maintained through clear differentiation between periods T1 and T2
3Adaptability or versatility
If waves with the same period are used to transmit data, then the transmission format is standardized, but the detection process becomes complicated
Solution Approach 1:
The patent changes the variable parameter from fixed period to variable period based on data bits. While maintaining wave standardization (still using periodic waves), the period length itself varies to encode data. This approach standardizes the wave format while making detection easier, as the receiving end simply measures period length rather than calculating duty ratios
