1Reliability
If channel encoding techniques (scrambler, convolution encoder, interleaving encoder, multi-level coding) are used to prevent channel effects and improve data transmission reliability, then data transmission reliability is improved, but encoding complexity increases significantly and requires numerous mathematical operations
Solution Approach 1:
The patent extracts and eliminates the complex channel encoding processes (scrambler, convolution encoder, interleaving encoder, multi-level coding) from the data transmission system. By removing these unnecessary encoding steps, the system achieves low encoding complexity while maintaining reliable data transmission through the straightforward spatiotemporal pattern image transmission method.
Solution Approach 2:
Instead of using complex encoding to protect data, the patent inverts the approach by using simple, direct transmission of spatiotemporal pattern images that are inherently resistant to channel effects. The system inverts the traditional wisdom by showing that complex encoding is unnecessary when using visual pattern transmission.
2Reliability
If traditional channel encoding techniques are used to handle channel effects, then error correction capability is enhanced, but the system requires reference to channel properties and extensive mathematical operations
Solution Approach 1:
The patent removes the requirement for channel property analysis and extensive mathematical operations from the data transmission system. By extracting these unnecessary elements, the system achieves error correction capability through simple spatiotemporal pattern recognition without needing to reference channel properties or perform complex calculations.
Solution Approach 2:
The spatiotemporal pattern image transmission system is self-sufficient and does not require external channel property information or complex mathematical processing. The system serves itself by using the inherent properties of visual pattern transmission to achieve reliable data communication without additional complexity.
3Productivity
