DATA COMMUNICATION METHOD BASED ON DUAL CARRIER MODULATION AND RELATED APPARATUS

摘要

Provided are a data communication method based on dual carrier modulation and a related apparatus. The method comprises: a first network device sending a first high-order modulation data stream on a first subcarrier and sending a fourth high-order modulation data stream on a second subcarrier; and a cooperative second network device sending a second high-order modulation data stream and a third high-order modulation data stream on the second subcarrier and the first subcarrier, respectively, wherein the first high-order modulation data stream and the second high-order modulation data stream are both obtained based on a first low-order modulation data stream and a second low-order modulation data stream, and the third high-order modulation data stream and the fourth high-order modulation data stream are both obtained based on a third low-order modulation data stream and a fourth low-order modulation data stream. Therefore, the first low-order modulation data stream to the fourth low-order modulation data stream can all be sent by different network devices on different subcarriers, thereby achieving space diversity and frequency diversity, and greatly improving the system performance.
