Multi-Antenna Diversity — A New Transmit Diversity Scheme for Wireless Communications
نویسنده
چکیده
In this paper, we propose multi-antenna diversity (MAD), a new transmit diversity scheme for wireless communications. Specifically, MAD selects the optimal transmit antenna with the best channel quality to send data. Due to its greatly simplified architecture, MAD guarantees the simple decoding without imposing any constraints on the issues such as code delay, code rate, antenna number, and modulation method, etc. We also develop the analytical framework to evaluate the performance of MAD from different perspectives. We show that MAD performs better than space-time block codes (STBC), while the processing complexity is lower than STBC. The superiority of MAD over STBC increases significantly as the number of transmit antennas gets larger.

This paper presents a simple two-branch transmit diversity scheme. Using two transmit antennas and one receive antenna the scheme provides the same diversity order as maximal-ratio receiver combining (MRRC) with one transmit antenna, and two receive antennas. It is also shown that the scheme may easily be generalized to two transmit antennas and M receive antennas to provide a diversity order o...

In a multi-user communication system, cooperative diversity allows single-antenna mobile sets to achieve transmit diversity. Cooperative diversity improves the communication capacity and enhances the robustness of a wireless link when a single channel alone is not reliable. In this paper, a novel cooperative diversity scheme is introduced that enables simultaneous transmission of non-redundant ...

In impulse-radio or DS/SS UWB communications, a prerake scheme has been proposed to achieve path diversity while reducing computational complexity in a mobile terminal. On the other hand, in an OFDM system, fractional sampling (FS) has been proposed to achieve path diversity with a single antenna. However, in the FS-OFDM system, it is necessary to oversample a received signal that leads to larg...

Abstract High speed data transmissions are required for the next generation mobile communication systems. However, broadband mobile channel is composed of many propagation paths with different time delays, producing severe frequency-selective fading channel. Recently, multi-carrier code division multiple access (MC-CDMA) has been attracting much attention for the broadband wireless access in th...
