Abstract
The present invention discloses a data transmission device and method thereof, and a data reception device and method thereof. The data transmission method in the present invention includes the following steps: encoding information data to obtain mother codes; generating transmission data including the mother codes and repetition codes from the mother codes, wherein parts of the mother codes with low reliability are selected to be repetition codes according to the modulation type of the mother codes; modulating the transmission data; transmitting the modulated data.
Claims22
A data transmission method, comprising:
- encoding information data to obtain a mother code;
- generating transmission data comprising the mother code and a repetition code, wherein the repetition code is selected from a part of the mother code having low reliability based on a modulation scheme of the mother code;
- modulating the transmission data;
- and
- transmitting the modulated data.
A data transmission apparatus, comprising:
- an encoder configured to encode information data to obtain a mother code;
- a data selector configured to generate transmission data comprising the mother code and a repetition code, wherein the repetition code is selected from a part of the mother code having low reliability based on a modulation scheme of the mother code;
- a modulator configured to modulating the transmission data;
- and
- a transmitter configured to transmit the modulated data.
A data reception method, comprising:
- receiving modulated data;
- demodulating the modulated data to generate a mother code and a repetition code, wherein the repetition code is a part of the mother code having low reliability that is selected based on a modulation scheme of the mother code;
- correcting the mother code based on the demodulated mother code and repetition code;
- and
- decoding the corrected mother code.
A data reception apparatus, comprising:
- a receiver configured to receive modulated data;
- a modulator configured to demodulate the modulated data to generate a mother code and a repetition code, wherein the repetition code is a part of the mother code having low reliability that is selected based on a modulation scheme of the mother code;
- a corrector configured to correct the mother code based on the demodulated mother code and repetition code;
- and
- a decoder configured to decode the corrected mother code.
