An arrangement where a transmitter has a plurality of transmitting antennas that concurrently transmit the same symbol, and where the signal delivered to each transmitting antenna is weighted by a factor that is related to the channel transmission coefficients found between the transmitting antenna and receiving antennas. In the case of a plurality of transmit antennas and one receive antenna, where the channel coefficient between the receive antenna and a transmit antenna i is h.sub.i, the weighting factor is h.sub.i.sup.* divided by a normalizing factor, .alpha., which is.times. ##EQU00001## where K is the number of transmitting antennas. When more than one receiving antenna is employed, the weighting factor is.times. ##EQU00002## where g=[g.sub.1 . . . g.sub.L], H is a matrix of channel coefficients, and .alpha. is a normalizing factor.times..times..times..times. ##EQU00003##
