Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing channel quality and resource allocation, particularly in multi-pulse multicarrier systems like QAM-FBMC, due to intrinsic interference and low frequency utilization efficiency, which affects data transmission rates and reception complexity.
Innovation Solution
A method for measuring channel quality and allocating resources using a filter bank approach, where channel state information is reported and resource allocation is managed per filter bank, allowing for differentiated modulation and coding schemes based on filter bank characteristics to optimize data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If filter bank-based modulation is used to improve frequency utilization efficiency, then data transmission rate is improved, but reception complexity increases due to intrinsic interference
Solution Approach 1:
The patent segments the frequency spectrum into multiple filter banks, each handling a specific frequency range. This segmentation allows independent optimization of each filter bank's performance and enables targeted resource allocation, reducing the overall reception complexity by dividing the complex task into manageable segments.
Solution Approach 2:
The patent applies different modulation and coding schemes to different filter banks based on their specific channel conditions. Each filter bank receives customized treatment tailored to its local characteristics, improving frequency utilization efficiency while managing reception complexity through localized optimization rather than uniform processing.
2Productivity
If resource allocation is optimized per filter bank, then frequency utilization efficiency is improved, but channel quality measurement complexity increases
Solution Approach 1:
The patent divides the channel quality measurement process into separate measurements for each filter bank. By segmenting the measurement task, the system can efficiently characterize each filter bank's channel conditions independently, enabling optimized resource allocation without overwhelming complexity in the measurement process.
Solution Approach 2:
The patent implements feedback mechanisms where receivers report channel quality information for each filter bank to the transmitter. This feedback enables the transmitter to adjust resource allocation dynamically based on actual channel conditions, improving frequency utilization efficiency while managing measurement complexity through structured information exchange.
3Productivity
If multiple filter banks are used to increase data transmission capacity, then productivity is improved, but intrinsic interference between filter banks increases
Solution Approach 1:
The patent assigns different modulation and coding schemes to different filter banks based on their individual channel conditions. This localized quality adjustment allows each filter bank to operate optimally with reduced interference, as each adapts its transmission characteristics to minimize impact on other filter banks while maximizing its own throughput.
Solution Approach 2:
The patent dynamically adjusts the operation of filter banks based on real-time channel conditions. By making the system dynamic rather than static, the patent can activate or deactivate specific filter banks as needed, adjusting their characteristics to minimize intrinsic interference while maintaining high data transmission capacity.
