Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for analyzing digitally modulated signals struggle to effectively remove irrelevant components and ensure the quality of modulation parameter analysis, as they rely on rigid algorithms that cannot adapt to varying input signals and lack a method to check the quality of intermediate steps.
Innovation Solution
A signal analysis method that progressively removes irrelevant components through multiple reduction stages, using either internal or external analysis routines, with the ability to adjust parameters based on previous results and external feedback, ensuring the signal is optimized for modulation parameter determination.

Engineering Contradiction Analysis
1Extent of automation
If a rigid specification of analysis algorithms is used, then the analysis process can be automated independently of the signal supplied, but the algorithm can only represent a compromise for all possible input signals and cannot check the quality of method steps
Solution Approach 1:
The patent implements a dynamic analysis algorithm that adapts its processing steps based on the characteristics of the input signal. The system evaluates signal properties and automatically adjusts the analysis methodology, transitioning from rigid predefined algorithms to flexible adaptive processing that optimizes precision for each specific signal type while maintaining automation.
Solution Approach 2:
The patent introduces quality check mechanisms that evaluate intermediate results of the analysis process. Feedback loops assess the effectiveness of each processing step and allow the system to adjust subsequent operations, enabling automated quality control without sacrificing automation extent.
2Measurement precision
If signal components that are not required for modulation analysis are removed, then the analysis precision is improved, but the device complexity increases due to multiple reduction stages
Solution Approach 1:
The patent divides the signal processing into multiple reduction stages, each targeting specific types of irrelevant signal components. By segmenting the complex reduction task into manageable sequential steps, the system achieves high precision modulation parameter determination while organizing device complexity in a structured, systematic manner.
Solution Approach 2:
The patent performs preliminary reduction of irrelevant signal components before the main modulation analysis. By removing unnecessary signal elements in advance through multiple reduction stages, the system simplifies the subsequent analysis process and improves precision without requiring overly complex real-time processing.
3Measurement precision
If external analysis routines are used, then the analysis can be optimized with known signal properties, but the device complexity increases due to interface and parameter management
Solution Approach 1:
The patent designs the interface and parameter management system to handle both internal and external analysis routines through a unified framework. The reduction parameters and interface mechanisms are designed to be universal, accommodating different signal types and analysis methods without requiring separate complex management structures for each case.

AI summary
The method involves reading in a signal, producing signal data as function of a physical parameter, and outputting the data over an interface (25) for an external analysis. External reduction parameters are read, when the analysis is accomplished, and internal reduction parameters are read, when the analysis is not accomplished. Reduction steps are accomplished based on the parameters. An evaluation of reduced signals is performed and the evaluation result is read. The reduced signal is forwarded for accomplishing further reduction steps with changed reduction parameters. Independent claims are also included for the following: (1) a digital memory medium with electronically readable control signals for the analysis of a digitally modulated signal (2) a computer program with program code for the analysis of a digitally modulated signal (3) a computer program product with program code for the analysis of a digitally modulated signal.
