Channel Coding by Repeated Bit Expansion for Passive IoT Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional channel coding schemes for passive IoT devices increase hardware complexity and power consumption while failing to ensure simplified implementation and transmission reliability.
Innovation Solution
Perform error correction coding on an information bit sequence to obtain a first coded bit sequence, and repeatedly expand it to obtain a second coded bit sequence, which is then sent to the receiving end, allowing for simplified processing and reduced power consumption.

Engineering Contradiction Analysis
1Reliability
If conventional channel coding schemes (sub-block interleaving, bit collection, bit selection) are used to reduce performance loss caused by sudden interference, then the resistance to sudden fading and interference is improved, but the hardware complexity increases and power consumption increases
Solution Approach 1:
The coded bit sequence is divided into multiple segments through repeated expansion operations. Each segment is a copy of the original coded sequence, allowing the receiving end to process segments independently and select the best one, thereby improving reliability without requiring complex interleaving or selection modules at the transmitter
Solution Approach 2:
The patent uses repeated copying of the coded bit sequence to create multiple identical segments. This simple copying mechanism replaces complex coding schemes like sub-block interleaving and bit collection, achieving interference resistance through redundancy rather than complexity
2Reliability
If conventional channel coding schemes (sub-block interleaving, bit collection, bit selection) are used to reduce performance loss caused by sudden interference, then the resistance to sudden fading and interference is improved, but the power consumption increases
Solution Approach 1:
The transmitting end simply copies the coded bit sequence multiple times without requiring complex processing operations. This copying approach consumes minimal power compared to conventional schemes that require active manipulation of bits through interleaving and selection operations
Solution Approach 2:
The repeated expansion structure provides inherent redundancy that automatically protects against interference without requiring additional power-consuming error correction operations at the transmitter. The receiving end benefits from this pre-prepared redundancy
3Reliability
If conventional channel coding schemes are used, then the resistance to sudden fading and interference is improved, but simplified implementation for tap devices of passive IoT is not achieved
Solution Approach 1:
The coded sequence is segmented into repeated blocks, creating a structure that is inherently simple to implement. Tap devices can easily process this segmented structure without requiring complex decoding algorithms, making it suitable for passive IoT applications
Solution Approach 2:
The patent changes the structural parameter of the coded sequence by repeating it multiple times, transforming a complex coding problem into a simple structural modification that is easy to implement while maintaining reliability
