Variable Pulse Width Encoding for Secure Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data encoding techniques are inadequate for secure and efficient information transmission, as they can be detected by standard protocol analyzers and do not effectively utilize signal characteristics to encode large amounts of information, leading to inefficiencies in data rate and security.
Innovation Solution
The use of variable pulse widths, phases, and amplitudes to encode binary data, allowing for the transmission of large amounts of information as single signal characteristics, which are difficult to detect and decode, thereby enhancing security and efficiency.

Engineering Contradiction Analysis
1Productivity
If conventional binary transmission is used, then the transmission system is simple and compatible with standard protocols, but the data transmission rate is low and security is compromised
Solution Approach 1:
The patent applies parameter changes by varying the pulse width duration to encode multiple bits of information. Instead of using fixed pulse widths for binary transmission, the system uses different pulse width values (e.g., 1 unit for '0', 2 units for '1', 3 units for '2') to represent different data values, thereby increasing the data transmission rate while maintaining protocol compatibility
Solution Approach 2:
The patent implements dynamics by making the pulse width variable rather than fixed. The pulse width dynamically changes based on the data being transmitted, allowing the system to convey more information per pulse while adapting to different data requirements, thus improving productivity without requiring completely new transmission infrastructure
2Difficulty of detecting and measuring
If standard pulse width encoding is used, then the transmission format is simple, but the communication is detectable by protocol analyzers
Solution Approach 1:
The patent applies composite encoding by combining multiple encoding dimensions: pulse width variation, bit reversal, and XOR operations with rotating keys. This composite approach creates a multi-layered encoding scheme that obscures the transmitted data from standard protocol analyzers while maintaining decodability at the receiver end through corresponding decoding operations
Solution Approach 2:
The patent implements preliminary action by pre-establishing rotating keys and performing bit reversal operations before transmission. These preliminary encoding steps transform the original data into an obscured format that prevents detection by standard analyzers, while the receiver can reverse these operations in sequence to recover the original information
3Quantity of substance
If variable pulse widths are used to encode multiple bits, then channel capacity increases, but signal synchronization becomes more difficult
Solution Approach 1:
The patent applies segmentation by dividing the variable pulse width signal into synchronized segments using start and stop bits. Each data transmission is framed with synchronization markers that allow the receiver to accurately identify pulse boundaries and timing, enabling precise measurement even when pulse widths vary to encode multiple bits of information
Data Source
AI summary
A communication device is provided for transmitting information incorporated into at least one message packet. The device includes components for encoding the message packet as a signal, which is afterwards transmitted and analyzed. The encoder assigns the message packet to correspond to a specific pulse width. The transmitter sends the signal across a channel. The processor parses the signal as corresponding to the specific pulse width subsequently decoded to obtain the message packet.
