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.

Massive MIMO for mmWave systems
2014 48th Asilomar Conference on Signals, Systems and Computers, 2014The large bandwidths available at the millimeter wave (mmWave) carrier frequencies (e.g., 30–100 GHz) have sparked significant interest in developing cellular systems in those bands to meet the ever-increasing demand for high data rates. Large-scale antenna arrays with tens or hundreds of antennas are envisioned to be a prerequisite for operating in ...

2017 IEEE Information Theory Workshop (ITW), 2017
In multiple-input multiple-output (MIMO) channels with discrete input alphabets, at high signal-to-noise ratio (SNR), maximizing the minimum Euclidean distance (d min ) between all possible received constellation points is known to be the optimal precoding strategy. However, finding the optimal precoder has been proved to be NP-hard.

Antenna selection in MIMO systems
IEEE Communications Magazine, 2004Multiple-antenna systems, also known as multiple-input multiple-output radio, can improve the capacity and reliability of radio communication. 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

Design Criteria of MIMO Systems
2006 IEEE 63rd Vehicular Technology Conference, 2006In this paper, the uncoded symbol error rate (SER) versus signal to noise ratio (SNR) curves of M-ary quadrature amplitude modulation (M-QAM) multiple-input multiple-output (MIMO) systems using zero-forcing (ZF) or maximum likelihood (ML) detection employing various numbers of antennas are given analytically and empirically.

ARQ protocols for MIMO systems
Third International Conference on Communications and Networking, 2012In this paper, we evaluate the performance of Automatic Repeat reQuest (ARQ) protocols for MIMO (Multiple In Multiple Out) Systems using fixed and adaptive Modulation based on the instantaneous Signal to Noise Ratio (SNR). Transmit Antenna Selection (TAS) or/and Space Time Block Coding (STBC) are used.

Simulation Platform for MIMO Systems
16th International Conference on Electronics, Communications and Computers (CONIELECOMP'06), 2006A computer simulator package for MIMO systems is presented. This simulator is highly configurable, easily extensible, and can generate exhaustive performance and complexity measurements. Examples of use and capabilities are shown. The simulatorÂ’s source code has been released to the research community under an open-source license.

Spatial mapping for MIMO systems
Manufacturing Engineer, 2005This contribution proposes a new spatial mapping technique for bit-interleaved coded modulation (BICM) over multiple-input multiple-output (MIMO) channels. It is an extension of conventional BICM whereby the serial-to-parallel converter is replaced with a more general mapping strategy.

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.
