1Productivity
If multi-level coding is implemented in wireless communication systems, then spectral efficiency can be improved, but coding complexity increases
Solution Approach 1:
The patent segments the coding process by applying different coding schemes to different modulation layers. Specifically, a first coding scheme is applied to first modulation layers while a second coding scheme is applied to second modulation layers, allowing independent optimization of each layer's coding complexity while maintaining overall spectral efficiency
Solution Approach 2:
The patent implements dynamic adaptation by selecting different coding schemes based on channel conditions. The system can dynamically switch between coding schemes for different modulation layers depending on the current wireless channel state, thereby optimizing the balance between spectral efficiency and coding complexity in real-time
2Quantity of substance
If multi-level coding is implemented in wireless communication systems, then data transmission capacity can be increased, but system complexity increases
Solution Approach 1:
The patent divides the data transmission system into multiple modulation layers with different coding schemes. This segmentation allows the system to handle different data streams independently, increasing overall data transmission capacity while managing system complexity through modular design
Solution Approach 2:
The patent creates a universal coding framework that can accommodate multiple coding schemes across different modulation layers. This multi-functional approach allows the same system architecture to handle various data transmission requirements, increasing capacity without proportionally increasing complexity
