Abstract
An OFDM communication system, a method and a device for transceiving signal are provided. The method includes: dividing M transmitting antennas into one or more groups to form U transmitting ports, wherein transmitting antennas in different groups are uncorrelated, and M is greater than or equal to U; forming P data flows using a Multiple-Input Multiple-Output (MIMO) mode, wherein P=U/2, and P is less than or equal to a number of receiving ports; and mapping a group of 2P modulation symbols, including two modulation symbols of each data flow, to a resource element pair to form Space Frequency Block Code (SFBC) coding relationships with each other, and transmitting the group of 2P modulation symbols on the U transmitting ports. The data transmission performance can be improved.
