Subscriber Station Error Correction in Serial Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Serial communication networks face high error rates due to bit errors, leading to increased transmission load and delays, as existing protocols require additional synchronization bits that do not carry information, thereby reducing effective data transmission rates.
Innovation Solution
A subscriber station for serial communication networks incorporates a communication control device that divides data into sections and inserts error correction code bits, allowing for error correction and synchronization without repeating transmissions, thus reducing error rates and increasing bit rates while eliminating unnecessary synchronization bits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional synchronization bits are inserted into the data stream to reduce bit error probability, then the error rate is reduced, but the transmission load increases and communication is delayed
Solution Approach 1:
The patent combines error correction functionality with synchronization functionality into a single integrated system. The error correction codes are designed to simultaneously provide both error correction capability and synchronization edges, eliminating the need for separate synchronization bits and reducing overall transmission overhead while maintaining reliability
Solution Approach 2:
The error correction code structure is designed to serve multiple functions: it corrects bit errors in the data stream while also providing synchronization edges for receiver alignment. This multi-functional approach reduces the total number of additional bits needed compared to separate error correction and synchronization mechanisms
2Reliability
If additional synchronization bits are inserted into the data stream to reduce bit error probability, then the error rate is reduced, but the bit rate is reduced
Solution Approach 1:
The patent merges error correction and synchronization functions into a single code structure, allowing the same bits to serve dual purposes. This reduces the overhead proportion and increases the effective bit rate compared to using separate mechanisms for each function
Solution Approach 2:
The patent optimizes the error correction code parameters (such as code rate and polynomial selection) to balance error correction capability with transmission speed. By carefully selecting code parameters, the system achieves adequate error protection while minimizing the impact on bit rate
3Reliability
If error detection is used to detect bit errors, then errors can be identified, but the message must be sent again increasing transmission load
Solution Approach 1:
The patent applies error correction codes in advance to the data before transmission. This preliminary error correction prepares the data so that any single-bit errors can be automatically corrected at the receiver without requiring retransmission, thus reducing transmission load while maintaining reliability

AI summary
The invention relates to a subscriber station (10; 20; 30) for a serial communication network (1), and to a method for correcting individual errors in a message (4; 5; 50) of a serial communication network (1). The subscriber station (10; 20; 30) comprises a communication control device (11; 21; 31) for creating a message (4; 5; 50), which is to be transmitted serially to at least one further subscriber station (20; 30; 10) of the communication network. The communication control device (11; 21; 31) is designed to divide the data of the message (4; 5; 50) that is to be created into at least one data portion (4521 to 452n) and to add bits (E) of an error correction code into each data portion (4521 to 452n), which enables at least one error in the message (4; 5; 50) to be corrected.
