Transmit/receive beamforming for bistatic multiple-input multiple-output (MIMO) radar
2014 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2014In this work, a coherent MIMO radar system operating in bistatic mode is considered. Orthogonal phase-coded waveforms are transmitted and the echo signals are digitally processed at the receiver. The simulation results show that the virtually formed bistatic-MIMO virtual array beampattern can achieve the optimal processing gain in the target direction.

Joint transmitter-receiver optimization for multiple input multiple output (MIMO) systems
The 57th IEEE Semiannual Vehicular Technology Conference, 2003. VTC 2003-Spring., 2004Multiple transmit (Tx) and multiple receive (Rx) antenna systems, referred to as multiple input multiple output (MIMO) systems, have been proposed to achieve higher data rates in wireless communication systems. In this paper, we investigate joint optimization of transmitter and receiver for MIMO system when the channel information is available at both ...

Multiple input/multiple output (MIMO) equalization for space-time block coding
1999 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (PACRIM 1999). Conference Proceedings (Cat. No.99CH36368), 2003In this paper, we propose to combine space-time block codes (ST-BC) with multiple input multiple output equalizer (MIMO-EQ) for achieving transmit diversity in a frequency selective Rayleigh fading channel. In the proposed system, MIMO-EQ equalizes the channel into a temporal intersymbol interference (ISI)-free channel, and then a simple linear ...

Mutual Information of Multiple-Input Multiple-Output (MIMO) Transmission Schemes
International Journal of Wireless Information Networks, 2005We analyze the mutual information of some common multiple-input multiple-output (MIMO) transmission schemes. Whereas most capacity evaluations are done under the assumption of Gaussian transmit symbols, we take into account restrictions on the transmit symbol alphabet and analyze real world signal constellations.
