Abstract
Provided are a data transmitting method, a data receiving method, a data transmitting device and a data receiving device. The data transmitting method comprises: modulating data in a first modulation manner to generate a first symbol stream; decomposing the first symbol stream into a pre-determined number of second symbol streams, each of which is modulated in a modulation manner with a modulation order lower than a modulation order of the first modulation manner; processing the pre-determined number of second symbol streams to generate a code-division-multiplexed data stream; and processing the code-division-multiplexed data stream to send the processed data stream. With the methods and the devices, reliability for data transmission can be improved.
