Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no existing technique for automatically estimating peak-to-average ratio (PAPR) communication parameters using the PAPR value of a transmission signal in receive apparatuses, limiting the efficiency of PAPR-based communication systems, especially in unidirectional and bidirectional modes.
Innovation Solution
A communication method that involves obtaining PAPR values from a lookup table, generating a synchronization signal based on these values, and transmitting it to automatically estimate PAPR communication parameters, allowing for synchronization between transmission and receive apparatuses without prior knowledge of communication parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If PAPR values are used to transmit digital information, then energy efficiency is improved for IoT devices, but automatic estimation of PAPR communication parameters in receive apparatuses is not available
Solution Approach 1:
The transmit apparatus performs preliminary actions by generating synchronization signals with specific PAPR characteristics and transmitting them before actual data communication. The receive apparatus uses these pre-transmitted signals to automatically estimate PAPR communication parameters (such as PAPR value, waveform shape, and timing) without requiring manual configuration, thereby enabling automated adaptation to the transmitted signal characteristics.
2Measurement precision
If synchronization signals are generated based on PAPR values from lookup tables, then communication parameter estimation is improved, but device complexity increases due to lookup table management
Solution Approach 1:
The lookup table is designed to store pre-calculated PAPR values corresponding to different data symbol configurations and modulation schemes. This universal table serves multiple functions: it provides reference values for synchronization signal generation at the transmit side, and serves as a reference for parameter estimation and demodulation at the receive side, thereby reducing the need for separate calibration procedures and reducing overall system complexity.
Solution Approach 2:
PAPR values and corresponding communication parameters are pre-calculated and stored in lookup tables before actual communication occurs. This preliminary preparation eliminates the need for real-time complex calculations during data transmission, reducing processing complexity while maintaining accurate parameter estimation through direct table lookup and comparison.
3Loss of time
If synchronization signals are transmitted for automatic parameter estimation, then communication setup time is reduced, but transmission overhead increases
Solution Approach 1:
The synchronization signal is designed to combine multiple functions into a single transmission: it provides timing synchronization, carries PAPR parameter information for automatic estimation, and enables waveform synchronization. By merging these functions into one signal structure, the patent reduces the number of separate signaling messages needed, thereby minimizing transmission overhead while achieving comprehensive communication setup.
