Abstract

Wireless CDMA cellular downlink communications with transmit antenna arrays in multipath fading channels is studied. Transmit diversity and various beamforming techniques are investigated and compared, in conjunction with power control. No instantaneous downlink channel information is assumed; however, the obtained results are also compared with results assuming ideal feedback. The study is carried out for both circuit-switched and packet-switched systems, for which different conclusions are drawn.
