Provided in an embodiment of the present invention are a data transmission method and device of a multi-aerial system, the data transmission method of the multi-aerial system comprising: conducting a first pre-code processing of the data to be transmitted in the first aerial direction of the multi-aerial system to generate first data; conducting second pre-code processing of the first data in the second aerial direction of the multi-aerial system to generate second data; transmitting the second data to a receiving node on each aerial port of the multi-aerial system; when the first pre-code processing is a first transmission diversity processing, the second pre-code processing is a second transmission diversity processing or second transmission spatial multiplexing processing, and when the first pre-code processing is a first transmission spatial multiplexing processing, the second pre-code processing is a second transmission diversity processing. The present invention utilizes aerials in multiple aerial directions of a multi-aerial system to transmit data. |
