The presence of fading in radio communications is the major impairment to reach the promised capacity. Diversity is a way to limit the fading effects and MIMO is a technique to exploit it. It is shown that in terrestrial mobile radio communications MIMO is an effective techniques while for satellite systems it requires further study to exploit possible

MIMO Systems With Adaptive Modulation
IEEE Transactions on Vehicular Technology, 2005Adaptive modulation (AM) schemes in multiple input multiple output (MIMO) systems with a perfect or imperfect channel state information (CSI) at both the transmitter and receiver were investigated. Under an average transmit power and instantaneous bit error rate (BER) constraint, the transmit parameters including the subchannel transmit power and/or ...

Spectral Coexistence of MIMO Radar and MIMO Cellular System
IEEE Transactions on Aerospace and Electronic Systems, 2017This paper details designing the precoder of a MIMO-radar spectrally-coexistent with a MIMO cellular system. Spectrum sharing with zero or minimal interference is achieved by using, respectively, the conventional switched null space projection (SNSP) or the newly proposed switched small singular value space projection (SSSVSP).

On the design of coded MIMO systems
2013 Third International Conference on Communications and Information Technology (ICCIT), 2013In this paper, we investigate two approaches which deal with the construction of space-time block (STB) codes for a system possessing a forward error correcting (FEC) code at the transmitter side. The first approach designs the STB codes to be optimal for a system equipped by a turbo MMSE equalizer at the receiver side, with a minimum peak to average ...

Synchronization for MIMO OFDM systems
GLOBECOM'01. IEEE Global Telecommunications Conference (Cat. No.01CH37270), 2002This paper proposes a time and frequency synchronization technique for a Q transmit and L receive (Q/spl times/L), MIMO OFDM system. The synchronization is achieved using training symbols which are simultaneously transmitted from Q transmit antennas. The training symbols are directly modulatable orthogonal polyphase sequences.

Decentralized Receiver in a MIMO system
2006 IEEE International Symposium on Information Theory, 2006In this paper we investigate the achievable rate of a system that includes a nomadic transmitter with several antennas, which is received by multiple agents, each with a single antenna, suffering independent channel coefficients and additive Gaussian noises. Since the transmitter is nomadic, the agents do not have any decoding ability.

On the capacity of cellular systems with MIMO
IEEE Communications Letters, 2002It is shown that the capacity of a single, isolated, multiple transmit and receive antenna array link, with given interference, is maximized by transmitting an independent data stream from each antenna for a quasistatic and flat Rayleigh fading channel with independent fading coefficients for each path.

Nonparametric decoupling of MIMO systems
2008 IEEE International Conference on Computer-Aided Control Systems, 2008The base functions approach has been recently proposed in the literature, in conjunction with digital finite impulse response (FIR) filters, as an effective method for set point tracking optimisation in single-input single-output (SISO) two-degree-of-freedom (2-d.o.f.) regulators.

Modulation Classification in MIMO Systems
MILCOM 2013 - 2013 IEEE Military Communications Conference, 2013Blind modulation classification is an important aspect of today's military systems and is projected to play equal important role in future cognitive radio systems. Modulation classification in MIMO systems present the added difficulty of having to deal with a set of mixed signals as they are received at the receiving antenna array.
