1. A base station having a plurality of transmitting antennas, the base station comprising:
means for transmitting from each transmitting antenna, a reference signal having a code uniquely associated with that antenna,
wherein the transmitted reference signals are not delayed with respect to each other; and
means for transmitting a data signal such that different spread spectrum versions of the data signal are transmitted from
each antenna, each data signal version having a different code for the respective transmitting antenna and the data signal
versions are not transmission channel compensation processed; and
wherein the base station transmissions are in a time division duplex format and weights derived from received versions of
the reference signals are used to weight received versions of the data signal versions prior to combining the weighted received
data signal versions.
