Solution Overview

Problem

Existing data transmission methods face challenges in ensuring reliability due to noise interference and bit errors, especially when data is transmitted through multiple channels.

Innovation Solution

A data receiving and sending method that utilizes two independent WLAN channels to transmit data, where each channel carries a part of the original data with an associated check field, allowing the receiving device to correct errors and improve transmission reliability by associating data from both channels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If channel coding technology is used to add error-correcting codes to original information, then data transmission reliability is improved, but device complexity increases due to encoding and decoding operations

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The original data is divided into multiple segments that are transmitted through different channels. Each segment contains a portion of the original information and corresponding check fields, allowing the receiver to reconstruct the complete data by combining segments from multiple channels while performing error correction on each segment independently.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Check fields are introduced as intermediary elements that mediate between the original information and the transmission channels. These check fields enable error detection and correction without requiring complex encoding schemes, as they provide reference data for verifying and correcting transmitted segments.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If data is transmitted through multiple channels to improve reliability, then error correction capability is enhanced, but system complexity increases due to multi-channel coordination

Engineering Contradiction:
Improveerror correction capabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The transmission system is segmented into multiple independent channels, each carrying a portion of the data with its own check fields. This segmentation allows each channel to be processed independently while contributing to the overall error correction capability when combined at the receiver.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent merges data from multiple channels by combining segments that were transmitted through different channels. The receiver integrates the segmented data and check fields from each channel to perform comprehensive error correction and reconstruct the original information, enhancing reliability through multi-channel collaboration.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If error correction is performed at the receiving device, then data reliability is improved, but processing time increases

Engineering Contradiction:
Improvedata reliabilityVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Check fields are prepared and attached to data segments in advance during the transmission phase. This preliminary action enables the receiving device to perform error correction more efficiently, as the verification data is already available without requiring additional real-time computation during the correction process.

Inventive Principle:
Principle #10Preliminary action

AI summary

A data receiving method is disclosed. The method includes: A wireless local area network (WLAN) receiving device receives, by using a first frequency module through a first channel, first data that is sent by a WLAN sending device. The WLAN receiving device receives, by using a second radio frequency module through a second channel, second data that is sent by the WLAN sending device. The WLAN receiving device obtains a received information field based on an information field of the first data and/or an information field of the second data. The WLAN receiving device obtains a received check field based on a check field of the first data and/or a check field of the second data. The WLAN receiving device attempts to check the received information field by using the received check field to obtain an original information field.
