Transmit diversity for arrays with correlated Rayleigh fading

Conference Record of the Thirty-Fourth Asilomar Conference on Signals, Systems and Computers (Cat. No.00CH37154), 2002
Transmit diversity is usually presented for the case of independently faded channels. In this paper the structure of a linear transmitter that can be optimized for a Rayleigh-fading environment in which the fading may be correlated is derived. The transmitter achieves the best mix of array gain-obtained by beamforming, and diversity gain-obtained by ...

Cooperative Transmit Diversity Utilizing Superposition Modulation

2007 IEEE Radio and Wireless Symposium, 2007
In this paper, the cooperative diversity with superposition modulation, which has been proposed as an instance of "dirty paper coding", is theoretically analyzed using the outage probability. We investigate the relationship between outage probability and transmission-rate corresponding to the parameter of superposition modulation.

Large-System Comparison of Space-Time Transmit Diversity and Orthogonal Transmit Diversity for Downlink W-CDMA

2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings, 2006
In this paper, we continue our study of the performance of W-CDMA transmit diversity (TD) that we started in B. Mouhouche et al. (2005). We compare the performance of two open-loop TD techniques for W-CDMA: The space time transmit diversity (STTD) and the orthogonal transmit diversity (OTD).
