Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Evaluating a base station, particularly an MU MIMO base station, is challenging due to the impact of various factors such as beamformers, equalizers, and channel conditions, making it difficult to control and isolate factors affecting performance, and designing propagation channels for testing is time-consuming and resource-intensive.
Innovation Solution
A base station testing system provides a graphical user interface (GUI) that includes selectable indicators for beam pattern analysis, allowing operators to visualize spatial frequency domain beam pattern analysis information, reducing the need for extensive computing resources and time by automating the creation of optimal propagation channels.

Engineering Contradiction Analysis
1Measurement precision
If traditional base station evaluation methods are used, then comprehensive performance assessment can be achieved, but the process becomes time-consuming and resource-intensive due to the need to control and isolate multiple factors
Solution Approach 1:
The patent extracts and isolates the beam pattern characteristics from the complex base station performance evaluation process. By using spatial Fourier transform to convert beam pattern data into spatial frequency domain representations, the system separates the key evaluation metric (beam pattern) from other interfering factors like beamformers and equalizers, enabling focused analysis without requiring control of all system variables
Solution Approach 2:
The patent introduces spatial frequency domain analysis as an intermediary representation layer between the physical beam patterns and the performance evaluation. The spatial Fourier transform acts as a mediator that converts complex spatial beam patterns into simplified frequency domain characteristics, making the evaluation process more efficient while maintaining accuracy
2Measurement precision
If traditional base station evaluation methods are used, then comprehensive performance assessment can be achieved, but extensive computing resources are required
Solution Approach 1:
The patent extracts only the essential beam pattern information from the complete base station signal processing chain. By focusing specifically on spatial Fourier transform of beam pattern data rather than analyzing all system components, the method reduces computational load while preserving the critical performance indicators needed for accurate evaluation
Solution Approach 2:
The patent creates a simplified computational model in the spatial frequency domain that replicates the essential characteristics of the physical beam patterns. This virtual representation allows performance evaluation without requiring full-scale physical testing or complete system simulation, significantly reducing computational resource requirements
3Ease of operation
If operators perform base station testing without automated beam pattern analysis, then detailed configuration knowledge is required, but the complexity of understanding beam and precoder information increases the difficulty of operation
Solution Approach 1:
The patent introduces spatial frequency domain analysis as an intermediary representation layer between the physical beam patterns and the performance evaluation. The spatial Fourier transform acts as a mediator that converts complex spatial beam patterns into simplified frequency domain characteristics, making the evaluation process more efficient while maintaining accuracy
Solution Approach 2:
The patent replaces manual analysis methods with automated computational processing. The spatial Fourier transform and graphical user interface automatically perform the complex analysis that would otherwise require operators to manually interpret beam and precoder information, substituting automated computational mechanics for human analytical effort
