Wireless transmission device, wireless receiving device, and method for transmitting encoded data

An encoded data transmission method comprising:

• first-encoding transmission data using a first encoding method and outputting the first-encoded data;
• first padding that adjusts size of the transmission data for the first-encoding by zero padding;
• second-encoding the first-encoded data using a second encoding method, and second-encoding the transmission data using the second encoding method independently of the second-encoding of the first-encoded data, and outputting second-encoded data;
• second padding that adjusts size of the transmission data for the second-encoding by zero padding, the size of zero padding of the second padding being same as that of the first padding;
• and
• transmitting the second-encoded data,
• wherein a coding unit length in the first-encoding is a natural number multiple of a coding unit length in the second-encoding.

A radio reception apparatus comprising:

• a reception section that receives first data, which is generated by first-encoding transmission data using a first encoding method, first padding that adjusts size of the transmission data for the first-encoding by zero padding, and second-encoding the first-encoded transmission data using a second encoding method, and second data, which is generated by second-encoding the transmission data using the second encoding method independently of the second-encoding of the first-encoded transmission data and second padding that adjusts size of the transmission data for the second-encoding by zero padding, wherein a coding unit length in the first-encoding is a natural number multiple of a coding unit length in the second-encoding, and the size of zero padding of the first padding is same as that of the second padding;
• a first decoding processing section that decodes the second data;
• an error detection section that performs error detection of the decoding result in the first decoding processing section;
• a deciding section that decides whether second decoding processing is necessary based on a condition of the error detection;
• and
• a second decoding section that decodes, when the decision result is that the second decoding processing is necessary, the first data using the second decoding processing.
