Bonded MoCA Channel LDPC Scheduling for Parallel Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coordinating hardware for parallel communication over multiple channels in home entertainment networks, such as those following the MoCA standard, is cumbersome and complex due to the need for independent calculation of LDPC forward error correction code parameters and padding bits by both transmitter and receiver nodes.
Innovation Solution
A method and apparatus for low-density parity check (LDPC) transmission over a bonded channel system, where data is divided into segments for the primary and secondary channels, with optimized forward error correction parameters and padding calculations to facilitate efficient coordination and scheduling across interconnected MoCA 2.0 SoCs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If parallel communication over multiple channels is implemented to increase information transmission capacity, then productivity is improved, but device complexity increases due to the need for coordination between channels
Solution Approach 1:
The data stream is segmented into multiple channels for parallel transmission. Each channel transmits a portion of the overall data, allowing the system to increase total throughput by utilizing multiple physical paths simultaneously while maintaining manageable complexity through structured data division
Solution Approach 2:
Multiple channel transmissions are merged at the receiver end to reconstruct the complete data stream. The coordination mechanisms combine information from parallel channels into a unified output, achieving high productivity while centralizing control logic to manage complexity
2Reliability
If independent calculation of LDPC parameters and padding bits is performed by both transmitter and receiver nodes to ensure reliable transmission, then reliability is improved, but device complexity increases
Solution Approach 1:
LDPC parameters and padding bit calculations are performed in advance during system initialization or connection setup. By pre-computing these parameters before actual data transmission begins, the system ensures reliable transmission without requiring complex real-time calculations during operation
Solution Approach 2:
Both transmitter and receiver nodes independently calculate and verify LDPC parameters using the same algorithms and input data. This self-service approach ensures both nodes have consistent understanding of transmission parameters without requiring complex coordination or centralized parameter distribution

AI summary
A particular overall architecture for transmission over a bonded channel system consisting of two interconnected MoCA (Multimedia over Coax Alliance) 2.0 SoCs (Systems on a Chip) and a method and apparatus for the case of a “bonded” channel network. With a bonded channel network, the data is divided into two segments, the first of which is transported over a primary channel and the second of which is transported over a secondary channel.
