A New Differential Space-Time Modulation Scheme for MIMO Systems with Four Transmit Antennas

Our goal is to show that it is possible to build powerful STTC codes with STBC designs with maximum transmission rate r = 1, even in the case where orthogonality

In this paper, we propose a new encoding scheme, based on the generalisation of Gabidulin codes to innite elds, which enables a polynomial time decoding.. This construction gives

Besides, the space diversity gain obtained with ZF SD tech- nique reaches the space diversity gain of MMSE SD tech- nique when using more transmit or more receive antennas

Abstract—In this paper, we propose, for the first time, QPSK super-orthogonal space-time trellis codes (SO-STTCs) with 3 and 4 transmit antennas and with more than 4 states.. In

As there is no preferred direction at the level of fundamental space, it means that in the emergent space-time physical laws are identical in all inertial frames of

The proposed combination of linear precoding and OSTBC applied to several transmit antennas leads to an efficient ex- ploitation of space, time and frequency diversities in
