Solution Overview

Problem

Communication systems face challenges in correcting interference over links due to concentrated errors, which conventional modulation schemes and error correction codes struggle to address effectively, leading to decoding failures and reduced data reliability.

Innovation Solution

The implementation of an interleaver and deinterleaver system, where the deinterleaver reverses the changes made by the interleaver to distribute errors across more data, ensuring balanced bit reliability and improved error correction by reordering bits and using error correction codes like Product Codes and LDPC codes, particularly in optical communication systems.

VSEngineering Contradiction Analysis

1Reliability

If conventional modulation schemes and error correction codes are used, then data transmission is achieved, but concentrated errors occur that lead to decoding failures and reduced data reliability

Engineering Contradiction:

Improvedata reliabilityVSAvoidconcentrated errors

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The deinterleaver divides the received data stream into multiple segments and redistributes them in a different order, breaking up concentrated error bursts into dispersed errors that can be more effectively corrected by error correction codes

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The deinterleaver reverses the interleaving process applied at the transmitter, undoing the error concentration effect and restoring the original data sequence order, thereby converting concentrated errors back into dispersed errors suitable for correction

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

If deinterleaving is implemented to distribute errors, then data reliability improves, but system complexity increases due to additional processing steps

Engineering Contradiction:

Improveerror correction capabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The interleaver performs preliminary error distribution before transmission, and the deinterleaver reverses this process at the receiver, allowing error correction codes to work more effectively without requiring complex real-time error handling mechanisms

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The deinterleaver acts as an intermediary component between the receiver and error correction decoder, transforming the error pattern into a form that the decoder can handle more efficiently, thereby improving overall system performance with moderate complexity addition

Inventive Principle:

Principle #24Intermediary (Mediator)
