Engineering Contradiction Analysis
1Use of energy by moving object
If OOK modulation is used, then power consumption is reduced, but data capacity is insufficient
Solution Approach 1:
The patent combines OOK modulation with phase modulation to create a hybrid scheme. The OOK component maintains power efficiency by using simple on-off keying, while the phase modulation component adds data capacity by encoding additional information in the phase of the signal. This merging allows the system to achieve both low power consumption and high data capacity simultaneously.
Solution Approach 2:
The patent transitions from one-dimensional OOK modulation (amplitude only) to two-dimensional modulation by adding phase information. This dimensional expansion allows the system to encode more information per symbol while maintaining the power-efficient OOK framework, effectively increasing data capacity without proportionally increasing power consumption.
2Device complexity
If OOK modulation is used, then device complexity is reduced, but timing precision is insufficient
Solution Approach 1:
The patent merges OOK modulation with phase modulation to create a hybrid scheme. The OOK component maintains simplicity and low device complexity, while the phase modulation component provides precise timing information through phase transitions. This combination allows the system to achieve accurate timing synchronization without significantly increasing device complexity.
3Loss of information
If phase modulation is added to OOK, then data capacity is improved, but device complexity increases
Solution Approach 1:
The patent segments the modulation scheme into distinct functional components: OOK for power-efficient amplitude control and phase modulation for data encoding. This segmentation allows each component to be optimized independently, with the OOK portion maintaining simplicity and the phase modulation portion providing enhanced data capacity, thereby limiting the overall increase in device complexity.
4Reliability
If beamforming and high-frequency communication are used, then communication performance is improved, but power consumption increases
Solution Approach 1:
The patent changes the modulation parameter from complex high-order modulation to a hybrid OOK-phase modulation scheme. This parameter change reduces the computational complexity and power consumption associated with signal processing, while maintaining communication performance through the phase information carried by the modulated signal.
