Effect of transmit antenna correlation on multiuser diversity
Proceedings. International Symposium on Information Theory, 2005. ISIT 2005., 2005In this paper, we investigate throughput performance of downlink multi-antenna transmission schemes exploiting multiuser diversity. The asymptotic analysis is performed based on the extreme value theory. From this analysis, it is demonstrated that the multiuser spatial multiplexing known as the asymptotically optimal transmission scheme is no longer ...

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).

A Transmit Diversity Scheme for TDS-OFDM System
IEEE Transactions on Broadcasting, 2008Transmit diversity is especially important in broadcasting network. In this paper, a transmit diversity method is proposed for the Chinese National Digital terrestrial television broadcasting (DTTB) standard. The transmit diversity scheme is based on the design of orthogonal sequences which have perfect crosscorrelation and almost perfect ...

Orthogonal Space-Time Spreading Transmit Diversity
IEICE Transactions on Communications, 2005In this paper, a new 2-antenna transmit diversity, called orthogonal space-time spreading transmit diversity (OSTSTD) combined with delay transmission, is proposed. At the transmitter, N data symbols to be transmitted are spread using N different orthogonal space-time spreading codes (each represented by N x N matrix) and are transmitted from two ...

Phase rotation Maximum Transmit Diversity code
Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011In order to improve the reliability of Maximum Transmit Diversity (MTD) code in block fading channel, phase rotation MTD code is proposed in this paper. Through phase rotation of the transmitted signals, the burst decoding error is changed into random error at the receiver, which can be corrected easily.

Antenna transmit diversity for wireless OFDM systems
Vehicular Technology Conference. IEEE 55th Vehicular Technology Conference. VTC Spring 2002 (Cat. No.02CH37367), 2003We investigate several transmit-diversity techniques for wireless OFDM systems employing multiple antennas. We concentrate our investigation on methods that can be applied with few modifications to existing standards. Existing methods such as delay diversity, clustering and antenna interleaving are investigated and compared.

On the matched filter bound of transmit diversity techniques
ICC 2001. IEEE International Conference on Communications. Conference Record (Cat. No.01CH37240), 2002Diversity transmission at the base station is an effective technique to combat the adverse effects of fading. This is suggested as an alternative to diversity at the terminal, thereby reducing the implementation complexity. We evaluate the matched filter bound (MFB) for two transmit diversity schemes with two transmit antennas: delay diversity and ...
