Shared Baseband Processing for Dual Radio-Optical Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices rely solely on either light or radio waves for transmission and reception, making them vulnerable to disruptions in either path, which can lead to communication failures if trouble occurs on the optical or radio transmission path.
Innovation Solution
A communication device configuration that uses both radio and optical carrier waves, modulated by pulse position modulation, allowing for shared baseband processing to ensure continuous communication even if one path fails, eliminating the need for separate baseband processing sections for each transmission and reception method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication devices use only light or radio waves for transmission, then the device structure can be simpler, but communication reliability deteriorates when trouble occurs on the transmission path
Solution Approach 1:
The patent combines both light wave and radio wave transmission systems into a single communication device, allowing the device to switch between transmission paths. The baseband processing section is shared between both transmission methods, merging functional components to maintain reliability while controlling complexity.
Solution Approach 2:
The baseband processing section is designed to be universal, serving both light wave and radio wave transmission functions. This multi-functional component processes signals for both transmission types, reducing the need for separate dedicated processing sections for each transmission method.
2Reliability
If separate baseband processing sections are provided for light and radio transmission, then transmission reliability improves, but device size and cost increase
Solution Approach 1:
The patent merges the baseband processing functions for light and radio transmission into a single shared baseband processing section. This consolidation maintains transmission reliability through redundant paths while significantly reducing device size and cost by eliminating duplicate processing components.
Solution Approach 2:
The baseband processing section is designed as a universal component that can handle both light wave and radio wave signal processing. This multi-functionality allows one processing section to serve multiple transmission purposes, reducing overall device complexity while maintaining reliable communication capabilities.
