Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If channel estimation and equalization are performed separately in the receiver, then processing flexibility is improved, but processing time and complexity increase
Solution Approach 1:
The patent combines channel estimation and equalization into a single joint processing operation at the receiver. Instead of performing channel estimation to obtain channel response values and then separately using those values for equalization, the receiver directly estimates equalized signal values by jointly processing the received signal and channel characteristics. This merging eliminates the sequential execution overhead and reduces processing time while maintaining the flexibility to adapt to different channel conditions through unified algorithm design.
2Loss of time
If joint channel estimation and equalization is performed, then processing time is reduced, but accuracy of channel response values deteriorates
Solution Approach 1:
The patent introduces pilot signals as an intermediary element to enable accurate channel estimation within the joint processing framework. These known pilot signals are embedded in the transmitted signal and used by the receiver to extract channel characteristics. The pilot signals act as a bridge that allows the joint estimation-equalization process to accurately determine channel response values while simultaneously performing equalization, thus maintaining measurement precision without requiring separate processing steps.
Solution Approach 2:
The patent performs preliminary channel characterization using pilot signals before the main data detection process. The receiver first uses the known pilot sequences to estimate channel responses, then applies these pre-obtained channel characteristics to the joint estimation-equalization process for data symbols. This preliminary action ensures that accurate channel information is available to guide the subsequent equalization operations, maintaining precision while enabling time-efficient joint processing.
3Measurement precision
If separate processing of channel estimation and equalization is used, then accuracy is maintained, but device complexity increases
Solution Approach 1:
The patent merges channel estimation and equalization into a single integrated processing block in the receiver. This unified structure uses common computational resources and data paths for both functions, eliminating the need for separate processing chains. The joint processor simultaneously extracts channel characteristics and performs equalization using shared algorithms and data structures, thereby reducing device complexity while preserving accuracy through coordinated processing of the received signal.
Solution Approach 2:
The joint processing architecture implements multi-functionality by using a single processing module that performs both channel estimation and equalization tasks. This universal processor can adapt its operation mode based on the input signal type (pilot or data symbols) and channel conditions, consolidating multiple specialized functions into one versatile component. This approach reduces the overall device complexity by eliminating redundant processing elements while maintaining the accuracy required for both estimation and equalization operations.
