Low Latency RF Transmission via Selective Error Coding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional radio frequency (RF) wave transmission methods incur high latency due to error coding overhead, which is necessary for signal integrity but increases processing delays, posing challenges for latency-sensitive applications like financial trading and requiring innovative approaches to reduce transmission latency while maintaining spectral efficiency.
Innovation Solution
The system employs selective error correction coding by distinguishing between latency-sensitive and insensitive data, using reduced or no error coding for sensitive data and maintaining signal integrity through separate treatment and modulation schemes, allowing for reduced latency and high spectral efficiency in long haul transport networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If error coding overhead is used to maintain signal integrity, then reliability is improved, but transmission latency increases
Solution Approach 1:
The patent segments data into latency-sensitive and latency-insensitive portions, applying different error coding strategies to each segment. Latency-sensitive data receives minimal or no error coding, while latency-insensitive data receives full error coding protection, thereby resolving the contradiction between reliability and latency for different data types
Solution Approach 2:
The patent applies local quality by using different error coding levels for different portions of the same transmission. Specifically, latency-sensitive data packets receive reduced error coding overhead while latency-insensitive data receives standard error coding, allowing each data type to have optimized properties for its specific requirements
2Loss of time
If reduced error coding is used for latency-sensitive data, then transmission latency is reduced, but signal integrity may be compromised
Solution Approach 1:
The patent divides the data stream into separate latency-sensitive and latency-insensitive segments, allowing reduced error coding to be applied only to latency-sensitive portions without affecting the integrity protection of other data, thus maintaining overall system reliability while reducing latency where needed
Solution Approach 2:
The patent changes the error coding parameter (coding overhead level) based on the latency sensitivity of the data. By dynamically adjusting the error coding parameter from standard levels to reduced levels for latency-sensitive data, the system achieves lower latency while maintaining adequate signal integrity through selective application

AI summary
An approach is provided for low latency radio frequency wave transmission. A long haul transport network receives a first signal representing latency sensitive data, receives a second signal representing latency insensitive data, and combines the first signal and the second signal to output a combined radio frequency signal, wherein the latency sensitive data of the combined radio frequency signal are at a first level of error coding, and the latency insensitive data of the combined radio frequency signal are at a second level of error coding.
