A common channel transmitter (112) at the base station (102) produces a first carrier signal to sequentially communicate, via divese transmission antennas, a pilot reference signal (111) to mobile stations (140). A dedicated channel transmitter produces a second carrier that communicates voice and signal traffic to the mobile station (140). At the base station (102) a sequencing switch (120) sequentially couples the common transmitter (112) to each of the transmission antennas (118, 128, 138) for sequentially transmitting the first carrier modulated with a pilot reference signal. A plurality of diverse receiving antennas (150, 160, 170), each corresponding to a respective one of the transmitter antennas (118, 128, 138), receive signals from the mobile station (140). The base station receiver provides respective signal to noise estimations indicating one of the antennas has a signal to noise ratio that is better than the signal to noise value provide by any other antenna. The base station (102) uses this antenna for the dedicated channel that is transmitted to the mobile station (140).
