Relay Device Communication Method for Satellite Signal Error Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In satellite communication systems, increasing transmission speed leads to deteriorated bit error rate performance due to geographical limitations and noise accumulation, particularly in relay communication systems where direct communication is hindered by spatial constraints.
Innovation Solution
A communication method and system that involves multiple relay devices, including small communication satellites, which receive and process signals from a first electronic device, divide data into pieces based on set rules, modulate and transmit these pieces as signals with different frequencies, and use multiplexing rules to identify and correct errors in received data, thereby improving bit error rate performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If transmission speed is increased, then productivity is improved, but bit error rate performance deteriorates
Solution Approach 1:
The transmitting terminal divides the data into multiple pieces and transmits them through different relay devices. Each relay device processes and forwards a portion of the data, allowing parallel transmission paths that maintain signal integrity even at high transmission speeds
Solution Approach 2:
Multiple relay devices are introduced as intermediaries between the transmitting and receiving terminals. These relay devices process, regenerate, and forward signals, compensating for signal degradation and maintaining reliability at high transmission speeds
2Adaptability or versatility
If relay devices are installed to overcome geographical limitations, then adaptability is improved, but noise accumulation increases
Solution Approach 1:
The data transmission is segmented across multiple relay devices, with each relay processing only a portion of the total data. This distribution reduces the noise accumulation impact at any single relay point
Solution Approach 2:
The receiving terminal performs error detection and correction on the received data pieces, and the system uses feedback mechanisms to identify and correct noise-induced errors, compensating for noise accumulation across multiple relays
3Reliability
If data is divided and multiplexed across multiple relay devices, then reliability is improved, but device complexity increases
Solution Approach 1:
The receiving terminal is designed with universal processing capabilities that can handle multiple pieces of data from different relay devices using the same demodulation and error correction algorithms, reducing overall system complexity despite the multiplexed input
