Abstract
A method and an apparatus for data signal transmission are disclosed. A data signal is coded through space-time-frequency coding to form k1 space-time-frequency bit streams. P of the k1 space-time-frequency bit streams are divided into Korthogonal components respectively, in which a modulus of an inner product of any two of the Korthogonal components is equal to zero or smaller than a set value. The data signal can be restored through the Korthogonal components, but cannot be restored though the remaining orthogonal components apart from any one non-zero orthogonal component. All orthogonal components are provided for virtual antennas of N base stations, and are mapped to Mphysical antennas of the base station for transmission.
