Solution Overview
Problem
Current pulse interference suppression methods in communication systems are complex and inefficient, particularly in environments where natural and human-induced interference cause significant disruptions, leading to potential physical damage and performance degradation, especially in transportation systems where measurement devices overlap with communication signals.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If characteristic analysis and matching are performed in transform domain to detect pulse interference, then detection accuracy is improved, but processing complexity increases significantly
Solution Approach 1:
The signal is divided into multiple segments in the time domain, and each segment is independently analyzed for pulse interference. This segmentation approach simplifies the processing by avoiding complex transform domain analysis while maintaining detection accuracy through localized power comparison of adjacent segments.
Solution Approach 2:
The patent extracts only the essential feature for pulse interference detection - the power difference between adjacent time segments - without performing full characteristic analysis in the transform domain. This extraction of key features reduces processing complexity while preserving detection capability.
2Reliability
If complicated signal processing is performed on interfered data to restore original signal, then signal quality is improved, but processing time increases
Solution Approach 1:
Instead of performing complicated restoration processing, the patent extracts and discards only the interfered data segments, keeping the uninterfered segments. This selective extraction approach maintains signal quality by preserving clean data while avoiding time-consuming restoration algorithms.
Solution Approach 2:
The patent discards the interfered data segments and relies on retransmission or error correction to recover the lost information. This approach trades the complexity of real-time restoration for simpler discarding operations, reducing processing time while maintaining reliability through recovery mechanisms.
3Measurement precision
If multiple pulse interference parameters are analyzed to identify interference location, then detection precision is improved, but implementation complexity increases
Solution Approach 1:
The patent extracts only the power parameter of adjacent time segments for interference location identification, ignoring other potential parameters. This single-parameter extraction approach achieves sufficient location precision while dramatically reducing implementation complexity compared to multi-parameter analysis.
Solution Approach 2:
By segmenting the signal in time and comparing power only between adjacent segments, the patent achieves precise interference location identification through simple local comparisons rather than global multi-parameter analysis, reducing implementation complexity.

AI summary
A method and apparatus for pulse interference suppression, and a computer readable storage medium in a communication system are provided in the embodiments of the present invention. The method includes: judging a location where pulse interference occurs according to a power of a signal; and performing suppression processing on a data segment interfered by a pulse in the location. After judging that the pulse interference exists in the location, a receiver in the communication system discards the data segment interfered by the pulse in the location, and feeds back an indication that the data are not received.
