Information Processing Device Using Segmented Pseudorandom Number Modulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Yuen-2000 protocol for data transmission at the physical layer faces a trade-off between increasing data transmission safety and rate, leading to higher costs and complex information processing devices, as it requires a large number of constellation points, which complicates design and resource usage.
Innovation Solution
An information processing device determines signal modulation reference points based on pseudorandom number information, segmenting it into types for disordering and modulation, allowing for improved data transmission safety and rate without significantly increasing costs by reducing the complexity of the information processing device.

Engineering Contradiction Analysis
1Reliability
If the number of constellation points is increased to improve data transmission safety and rate, then data transmission safety and rate are improved, but device complexity and costs increase
Solution Approach 1:
The patent segments the pseudorandom number information into multiple types (first, second, third pseudorandom number information) and processes each type separately through different disordering sections. This segmentation allows the system to achieve high transmission safety through multiple layers of randomization while keeping each individual processing section relatively simple, avoiding the need for a single complex large-scale constellation point system.
2Productivity
If the number of constellation points is increased to improve data transmission rate, then data transmission rate is improved, but computational resources and production costs increase
Solution Approach 1:
The patent divides the pseudorandom number generation into multiple segments (first, second, third pseudorandom number information) that are processed in parallel through separate disordering sections. This segmentation enables the system to achieve high data transmission rates by distributing the computational workload across multiple simpler processing units rather than requiring a single resource-intensive large constellation point system.
Solution Approach 2:
The patent combines multiple types of pseudorandom number information through different disordering processes to create the final signal modulation reference point. By merging multiple simpler randomization processes, the system achieves the equivalent security and rate performance of a complex large constellation point system while using fewer computational resources and reducing production costs.

AI summary
The present invention improves data transmission safety and data transfer rate, and reduces an increase in costs when doing so. A map management unit 141 manages a map which defines a prescribed rule for dividing pseudorandom number data into two. On the basis of the rule defined by the map, a division unit 142 generates data obtained by dividing the pseudorandom number data into two as vertically irregular mapping input data and horizontally irregular mapping input data. A vertically irregular mapping unit 151 generates data obtained by subjecting the vertically irregular mapping input data to irregular mapping processing as vertical base reference point data. A horizontally irregular mapping unit 152 generates data obtained by subjecting the horizontally irregular mapping input data to irregular mapping processing as horizontal base reference point data. A base reference point information generation unit 133 decides on one base on the basis of the vertical base reference point data and the horizontal base reference point data.
