Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The coexistence of optical fiber and wireless communication in existing systems results in different bit error thresholds, leading to performance waste and limited capacity improvement due to the higher bit error rate requirements of wireless communication.
Innovation Solution
A data transmission method that adds check and encoded bits to header information in data packets, enabling error correction and successful reception, thereby reducing the probability of header information check failures and maintaining throughput even in high-capacity scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different bit error thresholds are applied for optical fiber and wireless communication, then each communication type can meet its specific requirements, but the wireless side performance is wasted and system capacity improvement is limited
Solution Approach 1:
The patent applies different error correction strategies to different parts of the data transmission system. Specifically, it adds check bits and encoded bits to header information to ensure reliable transmission over optical fiber, while the wireless side can operate with its own tolerance for higher bit error rates. This local differentiation allows each communication path to be optimized independently.
2Productivity
If header information is transmitted without additional check and encoded bits, then transmission is simple and fast, but header information check failures occur frequently in high-capacity scenarios
Solution Approach 1:
The patent performs preliminary error correction by adding check bits and encoded bits to the header information before transmission. This preliminary action ensures that when the header information is received, any potential errors can be detected and corrected in advance, preventing check failures during high-capacity transmission scenarios.
3Reliability
If check bits are added to header information, then error detection capability is improved, but the data packet size increases
Solution Approach 1:
The patent changes the parameters of the header information by adding check bits and encoded bits. This parameter change increases the error detection and correction capability while the impact on overall packet size is minimized because only the header portion is modified, not the entire data payload.
