In this work, we consider the multiple access channel without channel side information at the transmitters, which have received considerable attention these last years. We propose a family of short distributed structured space-time codes achieving the diversity-multiplexing gain tradeoff (L. Zheng and D. Tse), (D.N. Tse,et.al) of this channel. We show that the designed codes outperform orthogonal...
We present a novel linear precoder design based on the minimum pair-wise error probability (PEP) criterion for general space-time block coded (STBC) MIMO systems. The channel state information at the transmitter consists of the channel mean and transmit antenna correlation matrices. Approximate joint diagonalization reveals the "average eigenstructure" shared by the mean and correlation...
Recently, the statistical properties of the equivalent channel representation of a multiple-input-multiple output (MIMO) system employing code rate one quasi-orthogonal space-time block codes (QSTBC), which are constructed by using orthogonal space-time block codes (OSTBC) as building elements, was characterized. Based on these characterizations we analyze the average rate (or mean mutual information),...
A new construction of a full-diversity full-rate space-time block code (FDFR-STBC) is presented in this paper. The design is for 2 transmit antennas and 2 time slots. The code outperforms the previous FDFR-STBC codes in [3], [4], [5], [6] for 1 receive antenna. We reduce the decoding complexity by exploiting the algebraic structure of the code and using the hybrid maximum-likelihood interference cancellation...
