Bonded MoCA LDPC Transmission with Coordinated Channel Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coordination of hardware in communications systems that use multiple channels simultaneously is cumbersome and complex, particularly in home entertainment networks like those following the MoCA standard, due to the need for independent calculation of LDPC forward error correction code parameters and padding bits by both transmitter and receiver.
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 calculations for reservation request parameters and FEC parameters optimized for efficient transmission across two interconnected MoCA 2.0 SoCs, allowing for easier coordination and scheduling of transmission slots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If parallel transmission over multiple channels is implemented, then information transmission capacity increases, but hardware coordination complexity increases
Solution Approach 1:
The patent segments the transmitted data into multiple channels (primary and secondary channels) for parallel transmission. Each channel carries a portion of the overall data stream, allowing simultaneous transmission over multiple physical media while maintaining independent channel management and reducing coordination overhead between channels.
2Reliability
If independent LDPC parameter calculation is performed by both transmitter and receiver, then transmission reliability is maintained, but coordination complexity increases
Solution Approach 1:
The patent implements self-service by enabling both the transmitter and receiver to independently calculate LDPC forward error correction code parameters and determine the number of padding bits without requiring complex coordination or exchange of parameter information between them. Each node autonomously performs the necessary calculations based on the channel conditions and transmission requirements.
3Productivity
If data is divided into segments for bonded channel transmission, then transmission efficiency improves, but calculation complexity for parameter optimization increases
Solution Approach 1:
The patent applies preliminary action by pre-calculating and optimizing the LDPC parameters and padding bit configurations for segmented data transmission across bonded channels. The system performs these calculations in advance based on channel characteristics and transmission requirements, storing the optimized parameters for reuse, thereby reducing real-time calculation complexity during actual transmission operations.

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.
