This letter deals with the identification of the number of transmitting antennas at a base
station. This estimation is achieved by exploiting the orthogonality between the pilot patterns
from each transmitting antenna. This orthogonality allows us to use multi-hypothesis testing
in order to enumerate the number of transmitting antennas using only one antenna at the
receiver. As a side product, the proposed algorithm allows us to estimate the channel gains
from all transmitting antennas and the noise variance.
