Abstract

In the 3^rd Generation Partnership Project (3GPP) time division CDMA (TD-CDMA) has been selected as the air interface for the TDD (time division duplexing) bands of 3^rd generation (3G) mobile radio systems. In this paper a novel multiuser transmission scheme for the TD-CDMA downlink is presented which in contrast to state of the art TD-CDMA transceivers utilizes the reciprocity of the mobile radio channels of the uplink and the downlink. It is shown that according to this scheme no channel estimation is necessary at the MSs and the data detection effort is dramatically reduced. The theoretical analysis of the paper is supported by computer simulation results which illustrate the superiority of the novel scheme in terms of the BER (bit error rate) performance and the system spectrum efficiency in the downlink of TD-CDMA
