Error Control Coding for Throughput Increase
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face inefficiencies in data transmission rates and high error rates, leading to increased latency and poor user experience due to the need for frequent retransmissions, which are not effectively addressed by existing coding schemes.
Innovation Solution
A system that employs an additional layer of error control coding by generating a second bit set with redundant data bits, allowing for selective transmission of these bits to assist the receiver in decoding, thereby reducing the number of retries and optimizing data transmission rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional coding schemes are used to control errors, then error rate is reduced, but data transmission rate is limited and retransmissions increase
Solution Approach 1:
The patent divides the redundant data bits into multiple sets (first redundant data bits and second redundant data bits) with different protection levels. The first set provides basic error correction while the second set provides enhanced protection, allowing the system to segment error correction capabilities and selectively transmit only when needed, thereby improving both reliability and transmission rate.
Solution Approach 2:
The patent applies partial error correction by transmitting only the necessary redundant data bits (first set) for basic error correction, and only transmitting the second set when errors are detected. This partial application of error correction mechanisms reduces overhead and increases transmission rate while maintaining adequate reliability for most conditions.
2Reliability
If more redundant data bits are added to improve error correction, then reliability increases, but transmission time increases due to additional data
Solution Approach 1:
The patent dynamically adjusts the amount of redundant data transmitted based on actual error conditions. The system first transmits only the essential first redundant data bits, and only if errors are detected does it transmit the additional second redundant data bits. This dynamic adaptation ensures minimal transmission time under normal conditions while maintaining high reliability when needed.
Solution Approach 2:
The patent uses partial error correction by providing basic protection through the first redundant data bits and only applying enhanced correction through the second set when necessary. This partial approach avoids the time penalty of always transmitting maximum redundancy while ensuring adequate error correction for most transmission scenarios.
3Reliability
If retransmissions are performed to correct errors, then data integrity is maintained, but latency increases and user experience deteriorates
Solution Approach 1:
The patent performs preliminary error correction by pre-calculating and transmitting the first redundant data bits that provide sufficient protection for most error conditions. This preliminary protection reduces the frequency of retransmissions by handling common errors locally at the receiver, thereby maintaining data integrity while reducing latency caused by repeated retransmissions.
Solution Approach 2:
The patent provides beforehand cushioning by including the first redundant data bits that act as a safety buffer against typical channel errors. This cushioning layer prevents many errors from requiring retransmission, thereby maintaining data integrity while minimizing the latency that would otherwise result from frequent retry mechanisms.

AI summary
A system and method for data coding and transmission for improving a retry mechanism are disclosed. A system and method allow the receiver to perform decoding based on increased data bits rather than by repeatedly processing the same retransmitted information, thereby reducing the number of retries and improving the performance of a communication system. Also, with the reduced number of retries, the computing costs of the electronic devices used in the communication systems are reduced. When mobile devices are often used in wireless communication, this is particularly advantageous since the battery life of these devices is significantly improved. Moreover, the system and method provide incremental data transmission and therefore optimize the utilization of channel bandwidth.
