Radio Communication System Self-Adjusting Receiver Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio communication systems require prior knowledge of the bandwidth of radio frequency signals for proper reception, limiting interoperability between radios from different manufacturers due to proprietary automatic link establishment (ALE) protocols.
Innovation Solution
A radio communication system that transmits an initial signal pattern at the beginning of each communication, allowing the receiving radio to derive communication channel parameters and radio frequency characteristics, enabling self-adjustment of receiving parameters without prior knowledge, and facilitating communication between radios from different manufacturers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If proprietary automatic link establishment (ALE) protocols are used to transmit bandwidth information, then the receiver can adapt its receiving parameters, but interoperability between radios from different manufacturers is limited
Solution Approach 1:
The receiver autonomously determines the bandwidth of the received radio frequency signal by analyzing the signal characteristics directly, without requiring any additional protocol or prior knowledge from proprietary ALE systems. This self-service approach eliminates dependency on manufacturer-specific protocols while maintaining the ability to adapt receiving parameters appropriately.
Solution Approach 2:
The bandwidth information is extracted directly from the radio frequency signal itself through signal analysis, rather than being transmitted separately through proprietary ALE protocols. This extraction method removes the dependency on manufacturer-specific communication protocols while preserving the essential information needed for receiver adaptation.
2Reliability
If the receiver requires a priori knowledge of bandwidth to adapt receiving parameters, then proper signal reception is enabled, but additional protocol complexity is introduced
Solution Approach 1:
The receiver determines the bandwidth autonomously by analyzing the received signal characteristics, eliminating the need for complex ALE protocols or external assistance. This self-determination approach maintains reliable signal reception while significantly reducing system complexity.
Solution Approach 2:
The bandwidth determination is performed as a preliminary step in the signal reception process, before the actual communication takes place. By determining the bandwidth upfront through signal analysis, the receiver prepares the necessary receiving parameters without requiring complex protocols during the communication phase.
3Loss of information
If proprietary ALE protocols are used to transmit transmitting parameters, then the receiver can obtain bandwidth information, but the system requires manufacturer-specific implementation
Solution Approach 1:
The bandwidth information is extracted directly from the radio frequency signal characteristics rather than being transmitted through proprietary ALE protocols. This extraction approach eliminates manufacturer-specific dependencies while ensuring that the receiver obtains the necessary bandwidth information for proper signal reception.
Solution Approach 2:
The signal analysis method is universally applicable to radio frequency signals from different manufacturers, as it relies on fundamental signal characteristics rather than manufacturer-specific protocols. This universal approach enables the receiver to obtain bandwidth information from any radio source without requiring proprietary implementations.
