Engineering Contradiction Analysis
1Loss of energy
If traditional power amplifier optimization methods are used, then power added efficiency is improved, but terminal power consumption performance remains poor
Solution Approach 1:
The patent changes the control parameter from fixed or simple feedback-based parameters to a probability distribution-based parameter (first parameter) that represents the statistical characteristics of output power. By optimizing the power amplifier's operating point based on the probability distribution of output powers, the system achieves better overall energy efficiency across varying communication conditions, resolving the contradiction between power added efficiency and terminal power consumption.
2Productivity
If general power amplifier control is applied, then basic functionality is maintained, but targeted optimization for specific operating conditions is insufficient
Solution Approach 1:
The patent performs preliminary analysis of the output power probability distribution before optimization. By pre-calculating the probability distribution of output powers and determining the first parameter in advance, the system enables targeted optimization for the most probable operating conditions. This preliminary action allows the power amplifier to be optimized for the most frequently encountered scenarios without requiring complex real-time adjustments, thus improving productivity while managing control complexity.
