Multiuser multi-input single-output (MISO) downlink systems, where one base station equipped with multiple antennas serves multiple single antenna mobile users, is of great interest recently. Significant capacity benefit can be obtained without extra time slots or spectrum. However, the number of simultaneously supportable users is limited by the number of transmit antennas. User selection is required...
An approach combining optimal antenna subset selection with blind detection scheme for Orthogonal Space-Time Block Coding (OSTBC) is proposed in this paper. The optimal antenna subset selection is taken into account at transmitter and/or receiver sides, which chooses the optimal antennas to increase the diversity order of OSTBC and improve further its performance. In order to enhance the robustness...
Multiple-antenna wireless communication systems have recently attracted significant attention due to their higher capacity and better immunity to fading as compared to systems that employ single-sensor transceiver. Increasing the number of transmit and receive antennas enables to improve system performance but at the price of higher hardware cost and computational burden due to the multiple RF chains...
Theoretical investigations have proven that the system combining beamforming with space-time block coding (STBC) in MIMO systems can improve the performance efficiently. However, the multiple RF chains associated with multiple antennas are costly in terms of size, power, and hardware. Antenna selection is a low-cost low-complexity alternative to capture many of the advantages of MIMO systems. In this...

Theoretical investigation have shown that multiple antenna schemes can improve link reliability and provide high spectral efficiency. Space-time block coding (STBC) and vertical Bell Labs layered space time (V-BLAST) systems are capable of meeting these requirements by using multiple antenna strategies, respectively. However, in order to achieve largely improved performance they need precise channel...
