And an external transmission control unit (21) that supplies the transmission module (22) with a redundant coding sequence obtained by redundant coding of transmission data.

Description

technical field [0001] The present invention relates to a transmitting device, a receiving device, a communication system, a control circuit, a communication method, and a storage medium using a fixed circuit whose internal processing sequence cannot be changed. Background technique [0002] Commonly used functionality is sometimes provided as a generic module. A general-purpose module is a fixed circuit whose internal processing order cannot be changed. In the communication field, frequently used functions such as high-frequency processing functions and digital modulation and demodulation processing functions are provided as modules. For example, Patent Document 1 discloses a demodulation method for FSK (Frequency Shift Keying) signals. Frequently used functions such as modulation processing and demodulation processing can reduce the time and labor for repeated development by using a common module.
