Engineering Contradiction Analysis
1Productivity
If customized signal processing methods are implemented using hardware-specific platforms (ASIC, DSP, FPGA), then processing performance is improved, but device complexity and implementation difficulty increase
Solution Approach 1:
The patent implements a universal signal processing platform that can handle multiple wireless communication standards (4G, 5G, and future protocols) through a single hardware architecture. The baseband processing unit and remote radio head are designed with configurable parameters that allow them to adapt to different protocols without requiring custom hardware design for each standard, thus reducing device complexity while maintaining high processing performance.
Solution Approach 2:
The system employs dynamic parameter configuration where the baseband processing unit and remote radio head can be reconfigured in real-time to support different wireless protocols and signal processing requirements. This dynamic adaptability eliminates the need for multiple static hardware designs, reducing overall system complexity while preserving optimized processing performance for each specific protocol.
2Productivity
If multiple specialized hardware platforms are used for different signal processing portions, then processing capability is improved, but ease of manufacture and integration deteriorate
Solution Approach 1:
The patent divides the wireless communication system into two main functional segments: a baseband processing unit and a remote radio head. Each segment is designed with standardized interfaces and configurable parameters that allow them to be manufactured separately and then easily integrated. This segmentation maintains specialized processing capabilities in each unit while simplifying the overall manufacturing and integration process through modular design.
Solution Approach 2:
Both the baseband processing unit and remote radio head are designed as universal modules that can support multiple wireless protocols through software configuration rather than hardware customization. This universality allows standardized manufacturing processes to be used across different deployments while maintaining the ability to perform specialized signal processing for various protocols through parameter adjustment.
3Measurement precision
If hardware-specific signal processing is implemented, then processing precision is improved, but adaptability to different protocols and environments deteriorates
Solution Approach 1:
The system implements dynamic parameter configuration that allows the baseband processing unit and remote radio head to adapt to different wireless protocols and environmental conditions while maintaining optimized signal processing precision. The configurable parameters enable the same hardware platform to achieve protocol-specific processing optimization without sacrificing adaptability, as the system can be reconfigured for each protocol to maintain precision while supporting multiple standards.
