Abstract  Abstract

A subscriber station for a CDMA cellular system that utilizes transmission diversity by transmitting a plurality of PN spread spectrum signals. Data is transmitted as PN spread spectrum modulated data signals where at least a first PN spread spectrum modulated data signal is formed by spreading and modulating the data with a first PN code and a second PN spread spectrum modulated data signal is formed by spreading and modulating the data with a second PN code which is different than the first PN code. The subscriber station has a receiver which receives the first and second PN spread spectrum modulated data signals. A despreader and demodulator despreads and demodulates the received PN spread spectrum modulated data signal using the respective PN codes. A combiner reconstructs the data from the despread and demodulated data signals. The PN spread spectrum modulated data signals are preferably transmitted in different time slots so that the receiver is configured to receive the PN spread spectrum modulated data signals in the respective slots. Preferably three PN spread spectrum modulated data signal are transmitted each from a different spaced apart antenna so that the subscriber station includes a measuring device for measuring respective times of arrival of the three data signals. A processor computes the location of the subscriber station from respective measured times of arrival of the data signals.
