1Measurement precision
If traditional detection algorithms are used in MIMO systems, then the system structure is simple, but the message recovery accuracy deteriorates under varying channel conditions
Solution Approach 1:
The patent applies dynamics by making the detector adaptive to changing channel conditions. The detector uses channel state information to dynamically adjust its detection strategy, transitioning from static traditional algorithms to dynamic adaptive detection that optimizes performance across varying channel states.
Solution Approach 2:
The patent changes detection parameters based on channel conditions. By utilizing channel state information, the system adjusts detection parameters such as threshold values, weighting factors, or algorithm selection to match current channel characteristics, thereby improving message recovery accuracy under different conditions.
2Productivity
If more antenna elements are added to improve data capacity, then the communication capacity increases, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing a detector that can handle multiple antenna configurations and various channel conditions through a unified adaptive framework. This multi-functional detector reduces the need for separate processing chains for different MIMO configurations, thereby managing complexity while supporting high-capacity communication.
Solution Approach 2:
The patent manages complexity through parameter changes by adjusting detection parameters based on the number of antenna elements and channel conditions. This allows the system to optimize performance for different antenna configurations without requiring fundamentally different detection architectures, thus controlling device complexity while maintaining high data capacity.

Solution Approach 1:
The patent applies dynamics by implementing adaptive signal processing that adjusts its complexity based on channel conditions. The detector dynamically selects processing intensity and algorithm complexity matched to the current channel state, avoiding unnecessary computational overhead while maintaining high message recovery accuracy when needed.
Solution Approach 2:
The patent manages processing complexity through parameter changes by adjusting detection algorithm parameters based on channel state information. This allows the system to optimize the trade-off between processing complexity and message recovery accuracy, using more sophisticated processing only when channel conditions warrant it.
