Abstract
The disclosure provides a non-orthogonal multiple access data transmission method and a transmission device using the same. The method includes: performing channel encoding for a plurality of data and a plurality of identifiers respectively corresponding to the plurality of data by using Raptor code so as to generate a Raptor codeword, wherein the plurality of identifiers respectively correspond to a plurality of receiving terminals; and modulating the Raptor codeword to generate a plurality of modulation symbols and broadcasting the plurality of modulation symbols.
Claims13
A transmission device adapted for non-orthogonal multiple access data transmission with a plurality of receiving terminals, comprising:
- a Raptor code encoding circuit that performs channel encoding for a plurality of data and a plurality of identifiers respectively corresponding to the plurality of data by using Raptor code so as to generate a Raptor codeword, wherein each of the plurality of identifiers corresponds to one of the plurality of receiving terminals and is used to identify the one of the plurality of receiving terminals;
- a modulation circuit coupled to the Raptor code encoding circuit, the modulation circuit modulating the Raptor codeword to generate a plurality of modulation symbols;
- and
- a first transceiver circuit coupled to the modulation circuit, the first transceiver circuit broadcasting the plurality of modulation symbols to the plurality of receiving terminals.
