Solution Overview

Problem

Satellite communication systems face challenges in efficiently managing variable bandwidth data streams from multiple sensors, requiring flexible and efficient framing and rate adaptation to maximize bandwidth aggregation, while minimizing data loss and allowing for dynamic changes in data rate and content without manual intervention.

Innovation Solution

A communication system comprising a data conversion module and a framer that processes multiple data streams, embedding channel identifiers and format indicators based on variable bandwidths, and a data interleaving apparatus with a multiplexing and transformation module that dynamically performs actions like rounding, truncation, and bit-width conversion on data streams to create self-describing superframes.

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual reconfiguration of PMP is performed to adapt to changes in data rate and content, then adaptability is improved, but loss of time increases due to manual intervention requirements

Engineering Contradiction:

Improveadaptability to changes in data rate and contentVSAvoidtime for manual reconfiguration

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system enables automatic reconfiguration by embedding format indicators and channel identifiers within data streams. Downstream electronics automatically detect these indicators and adapt to changes in data rate and content without requiring manual intervention, allowing the system to reconfigure itself in real-time

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent implements a feedback mechanism where format indicators and channel identifiers are continuously embedded in data streams, providing real-time information about data rate and content changes. This feedback enables automatic detection and adaptation by downstream processors

Inventive Principle:

Principle #23Feedback

2Productivity

If flexible framing and rate adaptation are implemented to maximize bandwidth aggregation, then productivity is improved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system dynamically changes parameters such as data rate, sample size, and format based on embedded indicators. This allows flexible bandwidth aggregation by adapting processing parameters to match actual data stream requirements rather than using fixed configurations

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent segments data streams into manageable units with embedded format indicators and channel identifiers. This segmentation allows independent processing of each data stream with appropriate parameters, simplifying the overall complexity by breaking down the processing into modular segments

Inventive Principle:

Principle #1Segmentation

3Device complexity

If data streams are processed with fixed bandwidth allocation, then device complexity is reduced, but loss of information increases due to inability to adapt to variable data rates

Engineering Contradiction:

Core Design Contradiction:

Device complexityVSLoss of information

Solution Approach 1:

The system transitions from static fixed bandwidth allocation to dynamic bandwidth allocation. Format indicators embedded in data streams enable real-time adjustment of processing bandwidth to match actual data requirements, preventing information loss while maintaining manageable system complexity through standardized adaptation mechanisms

Inventive Principle:

Principle #15Dynamics
