A Simple Transmit Diversity Technique for Wireless Communications

Lets see the abstract part of this paper:
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 of 2M. The
new scheme does not require any bandwidth expansion any
feedback from the receiver to the transmitter and its computation
complexity is similar to MRRC.

For my study i'm now studying this paper. So I'm sharing with you,if it may useful for you. Hope that it will be helpful for you.
