Solution Overview
Problem
Existing communication systems face challenges in efficiently transmitting data packets at different transmission rates, particularly when transitioning between high-speed and low-speed data transmission, which can lead to inefficiencies and errors in data recovery.
Innovation Solution
A communication apparatus and system that includes converters to convert low-speed packets into high-speed packets and vice versa, using hardware circuits to manage the transition and ensure reliable data transmission by generating and restoring packets with specific formatting and error correction techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data packets are transmitted at high transmission rates, then transmission speed is improved, but packet loss and errors increase when transitioning to low-speed channels
Solution Approach 1:
The patent changes the parameter of transmission rate dynamically. The communication system switches between first and second transmission rates (high and low) depending on channel conditions. This allows the system to maintain high speed when possible while ensuring reliability when transitioning to low-speed modes, resolving the contradiction between speed and reliability.
Solution Approach 2:
The patent implements feedback mechanisms where the communication apparatus monitors transmission quality and adjusts the transmission rate accordingly. This feedback loop enables the system to detect when high-speed transmission causes errors and automatically switch to lower speeds, maintaining both speed and reliability through adaptive control.
2Productivity
If low-speed packets are converted to high-speed packets, then transmission efficiency is improved, but packet generation complexity increases
Solution Approach 1:
The patent introduces an intermediary conversion mechanism that handles the transformation between packet formats. This intermediary layer abstracts the complexity of packet conversion from the main transmission logic, allowing efficient high-speed transmission while managing conversion complexity through dedicated processing components that handle the transformation between first and second transmission rates.
3Adaptability or versatility
If packets are transmitted sequentially at different rates, then adaptability to channel conditions is improved, but transmission time increases
Solution Approach 1:
The patent implements dynamic transmission rate adjustment based on real-time channel conditions. The system can switch between high and low transmission rates dynamically, allowing adaptability to varying channel quality. This dynamic approach optimizes the balance between transmission speed and adaptability, reducing unnecessary delays while maintaining channel adaptation capabilities.
Data Source
AI summary
A first communication apparatus is configured to transmit a first packet at a first transmission rate, and includes a first interface, a generation unit, and a second interface. The first interface is configured to receive a second packet transmitted at a second transmission rate lower than the first transmission rate. The generation unit is configured to, each time the first interface receives a second bit group having number of bits smaller than the number of bits of a data main body that can be included in the first packet out of a first bit group to be transmitted included in the second packet, sequentially generate the first packet including the data main body including the second bit group. The second interface is configured to, each time the generation unit generates the first packet, sequentially transmit the first packet.
