In this paper, important dynamic characteristics of MIMO mobile fading channels such as the level crossing rate (LCR) and average fade durations (AFD) are studied. Depending on the application, either a scalar crossing approach or a vector crossing approach is taken, and appropriate definitions for LCR and AFD in MIMO channels are provided. The more general concept of average stay duration (ASD...

Beamspace MIMO (BS-MIMO) systems have been recently proposed as a means to address the two key weaknesses of conventional MIMO systems: the antenna size and the need for multiple RF chains. BS-MIMO transmission is supported by the Electronically Steerable Passive Array Radiators (ESPAR) with a single active and multiple parasitic elements. The main objective is to develop efficient MIMO multipl...

For future wireless communications systems, parameters like high transmission data rate, spectral efficiency, and reliability are extremely necessary. In a multipath wireless channel, deploying multiple antennas at both the transmitter and receiver help us achieve higher data rate without increasing the total transmission power or bandwidth. When perfect knowledge of the wireless channel condit...

In this paper, we focus on the diversity-multiplexing tradeoff (DMT) in MIMO channels and introduce the development of DMT in MIMO channels. Zheng and Tse first proposed DMT in MIMO channels and based on their ideas, other researchers extended to many different aspects. We will study DMT in different MIMO fading channels, DMT curves and DMT under different protocols.

In this paper, we investigate adaptive blind source separation and equalization for multiple-input/multiple-output (MIMO) systems. We first analyze the convergence of the constant modulus algorithm (CMA) used in MIMO systems (MIMOCMA). Our analysis reveals that the MIMO-CMA equalizer is able to recover one of the input signals, remove the intersymbol interference (ISI), and suppress the other i...

This paper proposes a Multiples Input-Multiples Ouput Autoregressive (MIMO-AR) model based on two stages to improve monthly anchovy catches forecasting of the coastal zone of Chile for periods from January 1958 to December 2011. In the first stage, the stationary wavelet transform (SWT) based on Fejer-Korovkin (FK) wavelet filter is used to separate the raw time series into a high frequency (HF...

In this paper, we consider a MIMO networked control system with an energy harvesting sensor, where an unstable MIMO dynamic system is connected to a controller via a MIMO fading channel. We focus on the energy harvesting and MIMO precoding design at the sensor so as to stabilize the unstable MIMO dynamic plant subject to the energy availability constraint at the sensor. Using the Lyapunov optim...

In this paper, we propose algorithms for signal detection in large-scale multiuser spatial modulation multipleinput multiple-output (SM-MIMO) systems. In large-scale SMMIMO, each user is equipped with multiple transmit antennas (e.g., 2 or 4 antennas) but only one transmit RF chain, and the base station (BS) is equipped with tens to hundreds of (e.g., 128) receive antennas. In SM-MIMO, in a giv...

A DECADE has passed since the pioneering works in which multiple-input multiple-output (MIMO) wireless systems have been introduced. By using multiple antennas at both link ends, MIMO in theory offers tremendous rate and reliability gains. These promises have spurred an extraordinary amount of research activities. By now, MIMO has become a well-established research topic, with thousands of pape...
