DATA SENDING AND RECEIVING METHOD, ANDA DATA SENDING AND RECEIVING DEVICE
First Claim
1. A data transmitting method, comprising:
- 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 that 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.

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.
