Abstract
Reliable detection of the configuration of transmit antennas includes obtaining a data for transmission, encoding the data, and modulating the data. During the modulating of the data, the data may be configured in such a way as to convey the configuration of the antennas through the modulation of the data. An antenna configuration is obtained by obtaining a representation of the antenna configuration, and masking the data with an error correcting code, where the mask corresponds to the antenna configuration.
