Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional error correction processing is used in varying propagation path conditions, then reliability is improved, but latency increases and receiver load increases
Solution Approach 1:
The patent applies preliminary action by pre-notifying the encoding processing manner to the receiver before data transmission. This allows the receiver to prepare the appropriate decoding configuration in advance, eliminating the need for iterative decoding attempts and reducing latency while maintaining reliability in varying propagation conditions.
Solution Approach 2:
The patent introduces an intermediary mechanism (the notification signal carrying encoding manner information) that bridges the transmitter and receiver. This intermediary enables the receiver to understand the encoding scheme beforehand, reducing decoding complexity and latency without compromising error correction reliability.
2Reliability
If conventional error correction processing is used in varying propagation path conditions, then reliability is improved, but receiver load increases
Solution Approach 1:
By pre-notifying the encoding processing manner, the receiver can configure its decoding process in advance, avoiding complex iterative decoding attempts. This reduces the computational load and processing complexity at the receiver while maintaining reliable error correction.
Solution Approach 2:
The notification signal acts as an intermediary that provides the receiver with essential decoding information beforehand. This reduces the complexity of receiver processing by eliminating the need for multiple decoding attempts and complex adaptive algorithms.
3Measurement precision
If encoding scheme is selected based on frequency band, then decoding performance is improved, but device complexity increases
Solution Approach 1:
The system applies self-service by having the transmitter automatically select and notify the appropriate encoding scheme based on frequency band characteristics. This eliminates the need for complex negotiations or feedback mechanisms between transmitter and receiver, reducing overall device complexity while maintaining optimal decoding performance.
Solution Approach 2:
The patent changes the encoding scheme parameter based on frequency band characteristics. By notifying the selected encoding manner to the receiver, the system achieves optimal decoding performance for different frequency bands without requiring complex adaptive mechanisms at both ends.

AI summary
A communication device (20 and 40) includes a redundant data generation unit (212a and 412a), a signal generation unit (212b, 412b, 212c, and 412c), and a transmission unit (212d and 412d). The redundant data generation unit (212a and 412a) performs error correction coding processing on combined data obtained by combining first data and second data to generate redundant data used for error correction. The signal generation unit (212b, 412b, 212c, and 412c) generates a transmission signal based on the second data and the redundant data. The transmission unit (212d and 412d) transmits the transmission signal to another communication device (20 and 40) .
