Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lack of standardization in signal processing by receiving devices in communication standards leads to interoperability issues between devices from different manufacturers, especially when interference is present, causing poor communication performance.
Innovation Solution
A communication method and device that includes a receiving circuit, a transmitting circuit, and a training circuit, which initializes a link, processes training commands to obtain a being-trained log, and adjusts transmission characteristics to improve interoperability by sending a training command string to adjust the corresponding device's transmission settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the receiving device independently determines and processes noise and random interference without standardized signal processing manners, then the device can operate with greater flexibility, but interoperability between devices from different manufacturers deteriorates
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting equalizer coefficients and transmission characteristics based on training commands and channel conditions. The receiving device processes training commands to generate being-trained logs, which are then used to optimize transmission parameters such as equalizer settings, thereby achieving both adaptability to different channels and standardized interoperability through the training protocol
Solution Approach 2:
The patent implements feedback mechanisms where the receiving device sends training command strings back to the transmitting device based on processed training commands. This feedback loop allows the transmitting device to adjust its transmission characteristics according to the receiving device's analysis results, ensuring interoperability while maintaining flexibility in signal processing
2Device complexity
If the communication standard only standardizes the transmitting device's signal transmission manner, then the standard implementation is simpler, but communication performance deteriorates when interference is present in the channel
Solution Approach 1:
The patent applies preliminary action by implementing a training procedure before actual data transmission. The transmitting device sends training commands that allow the receiving device to pre-adjust its equalizer coefficients and analyze channel characteristics. This preliminary calibration ensures optimal communication performance when interference is present, while the standardized training protocol keeps implementation complexity manageable
Solution Approach 2:
The patent implements dynamics by making the transmission characteristics adjustable based on channel conditions. The training circuit generates being-trained logs that dynamically optimize equalizer settings and transmission parameters according to the actual channel state. This dynamic adjustment capability improves communication performance in interfered channels while maintaining standardized implementation through the training command protocol

AI summary
A communication device is adapted to perform a communication method. The communication method includes: initializing a link between the communication device and a corresponding device; responding to a being-trained procedure to obtain a being-trained log; and sending a training command string according to the being-trained log. Therefore, the corresponding device adjusts its transmission characteristic according to the received training command string to reach appropriate interoperability between devices.
