Title:
DATA TRANSMISSION METHOD, DATA TRANSMITTING DEVICE AND DATA RECEIVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/121248
Kind Code:
A1
Abstract:
A data transmission method, data transmitting device and data receiving device. The data transmitting device encodes information data using a low density parity check (LDPC) code matrix so as to obtain a bit sequence, the bit sequence comprising a first bit sequence, and the first bit sequence comprising at least one information bit in the bit sequence; the data transmitting device interleaves the first bit sequence so as to obtain a first interleaved bit sequence; and the data transmitting device modulates according to the first interleaved bit sequence so as to obtain a transmission signal and transmits the transmission signal. The data receiving device obtains a soft value sequence by means of demodulating a received signal; and the data receiving device de-interleaves the soft value sequence so as to obtain a soft value sequence of the first bit sequence, and may thus improve the capabilities of an LDPC code in resisting against burst interference.
