Downlink Space-Frequency Preequalization Techniques for TDD MC-CDMA Mobile Radio Systems

EURASIP Journal on Wireless Communications and Networking, 2004
The paper considers downlink space-frequency preequalizations techniques for time division duplex (TDD) MC-CDMA. We consider the use of antenna arrays at the base station (BS) and analytically derive different preequalization schemes for two different ...
