A transmitting station for communicating data in a CDMA cellular system
that utilizes transmission diversity by transmitting a plurality of PN
spread spectrum signals. The transmitting station spreads and modulates
the data with a plurality of different PN codes to form a plurality of PN
spread spectrum modulated data signals. A transmitter transmits the PN
spread spectrum modulated data signals from the transmitting station.
Preferably, the transmitter includes multiple spaced apart antennas from
which the respective PN spread spectrum modulated data signals are
transmitted. Preferably, the transmitter is configured to transmit the PN
spread spectrum modulated data signals as a plurality of time slotted PN
spread spectrum signals, each PN spread spectrum modulated data signal in
a different time slot. In one embodiment, a PN code generator operates in
conjunction with the forming the PN spread spectrum modulated data signals
during different time intervals corresponding to the different time slots
so that the PN codes used to spread the data are part of a PN code
sequence produced by the PN code generator without resetting.
