Solution Overview
Problem
Current methods for detecting Digital Intermediate Frequency (DIF) processing systems face challenges such as low accuracy, inability to locate faults, high detection costs, and low efficiency due to indirect detection and the need for extensive setup environments.
Innovation Solution
A method and apparatus that involve forming and sending excitation data to the DIF processing system, collecting detection data, and comparing it bit-by-bit with reference data to directly assess processing accuracy, using existing structures within the Remote Radio Unit (RRU) without additional hardware like spectrometers or signal sources, allowing for accurate fault identification and reduced setup requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If overall detection on RRU transmission data is performed, then detection coverage is improved, but detection accuracy deteriorates
Solution Approach 1:
The patent segments the detection process by isolating the DIF processing system from the overall RRU transmission data flow. It extracts specific intermediate frequency processing data for dedicated detection, separating the detection target from the complete transmission chain. This segmentation enables precise bit-level comparison of DIF processing results without the complexity of setting up complete RRU transmission environments.
2Measurement precision
If bit-level detection is performed on DIF processing, then detection accuracy is improved, but detection difficulty increases
Solution Approach 1:
The patent extracts the essential detection elements (excitation data input and detection data output) from the complex DIF processing system. By taking out only the necessary components for bit-level comparison and eliminating unnecessary detection environment elements, it reduces detection difficulty while maintaining high accuracy. The extraction focuses on the core processing chain that can be tested in isolation.
3Measurement precision
If direct detection on DIF processing system is performed, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service detection by utilizing the DIF processing system's own internal data flow for detection purposes. The system uses its excitation data input and intermediate frequency processing output for self-diagnosis, eliminating the need for external spectrometers, signal sources, and complex detection equipment. This self-service approach enables direct detection without increasing device complexity.
4Adaptability or versatility
If multiple communication modes are detected, then system versatility is improved, but detection time increases
Solution Approach 1:
The patent creates a universal detection method that can handle multiple communication modes through a single unified detection framework. The detection apparatus uses the same excitation data generation, data collection, and bit-level comparison process regardless of the communication mode being tested. This multi-functional approach allows versatile detection of different modes without requiring separate detection environments or procedures for each mode.
