To more efficiently realize the coded multiple-input multiple-output (MIMO) transmission and improve the system performance, in this paper, we propose a framework combining the polar coding and the MIMO technique, namely the polar-coded MIMO (PC-MIMO) systems.

We investigate the performance of a DS/CDMA system with multiple-input multiple-output (MIMO) antenna processing in the downlink. We formulate the weights for the transmit and receive antennas by trying to obtain the optimum signal-to-interference-plus-noise ratio (SINR) in a frequency selective fading channel. The gain of our MIMO CDMA system with the

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.

To alleviate the high peak-to-average power ratio (PAPR), high complexity in user terminal and sensitivity to carrier frequency offset (CFO) problems in current OFDMA systems, a Quadrature OFDM (Q-OFDMA) system has been recently proposed in the single-input single-output environment.

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 ...

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.

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
