Dual-Path Interference Suppression for Wireless Signal Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional interference suppression methods in wireless networks fail to effectively address intra-cell interference, leading to increased processing costs and reduced signal integrity, as they primarily focus on inter-cell interference and leave intra-cell interference for downstream processing.
Innovation Solution
The implementation of a dual-path structure within the PRISM module, incorporating both inter-cell and intra-cell interference suppression modules, which allows for simultaneous suppression of inter-cell and intra-cell interference before the equalization stage, reducing downstream processing costs and enhancing signal integrity.

1Object-affected harmful factors
If conventional interference suppression methods are used that focus on inter-cell interference, then inter-cell interference is suppressed, but intra-cell interference remains and increases processing costs and reduces signal integrity
Solution Approach 1:
The interference suppression module is segmented into two distinct paths: an inter-cell interference suppression path and an intra-cell interference suppression path. This segmentation allows each path to specialize in suppressing specific types of interference, thereby improving overall signal integrity while managing processing resources efficiently.
Solution Approach 2:
The intra-cell interference suppression is performed preliminarily before the downstream equalization stage. By suppressing intra-cell interference in advance, the system reduces the processing burden on downstream equalizers and improves signal integrity before further processing occurs.
2Productivity
If intra-cell interference is left for downstream processing, then current processing costs are reduced, but downstream processing costs increase and signal integrity deteriorates
Solution Approach 1:
The system performs intra-cell interference suppression as a preliminary action before downstream equalization. This preliminary suppression reduces the complexity and processing costs of downstream equalizers by removing interference early in the processing chain.
Solution Approach 2:
The processing system is segmented into distinct stages with dedicated functions: inter-cell interference suppression, intra-cell interference suppression, and downstream equalization. This segmentation allows each stage to operate independently with optimized processing requirements, reducing overall system complexity.
3Reliability
If a dual-path structure with both inter-cell and intra-cell suppression is implemented, then signal integrity is enhanced, but device complexity increases
Solution Approach 1:
The PRISM module is segmented into two functional paths within the interference suppression module: one for inter-cell interference suppression and another for intra-cell interference suppression. This segmentation enables specialized processing for each interference type while maintaining modular architecture that manages complexity.
Solution Approach 2:
The interference suppression module serves multiple functions by handling both inter-cell and intra-cell interference suppression within a single integrated component. This multi-functionality enhances signal integrity while consolidating processing functions to manage overall device complexity.

AI summary
In one embodiment, interference suppression is improved by improving convergence criteria. For some embodiments, convergence is improved by employing non-constant alpha-beta-weighting. For other embodiments, convergence is improved by employing successive interference suppression methods that have guaranteed convergence properties.
