1Robust Design for Amplify-and-Forward MIMO Relay Systems with Direct Link and Imperfect Channel Information
"... Abstract—In this paper, we propose statistically robust design for multiple-input multiple-output (MIMO) relay systems with the direct source-destination link and imperfect channel state in-formation (CSI). The minimum mean-squared error (MMSE) of the signal waveform estimation at the destination no ..."

Simulation results demonstrate an improved performance of the proposed algorithms with respect to the conventional

EURASIP Journal on Applied Signal Processing 2005:11, 1712–1724 c ○ 2005 Uwe Trautwein et al. Measurement-Based Performance Evaluation of Advanced MIMO Transceiver Designs
, 2005
"... This paper describes the methodology and the results of performance investigations on a multiple-input multiple-output (MIMO) transceiver scheme for frequency-selective radio channels. The method relies on offline simulations and employs real-time MIMO channel sounder measurement data to ensure a re ..."

The dependency of the achievable bit error rate performance on the propagation characteristics and on the variation in some system design parameters is shown, whereas the antenna constellation is of particular
Signal processing algorithms and architectures for communication transceivers
, 2004
"... Several transmit and receive processing techniques are studied and extended within this thesis: motivated by the ever increasing demand for high quality and high rate physical layer communication links. Two novel transmitter preprocessing techniques for quasi-orthogonal space-time block-code (QO-STB ..."

MIMO space-time coding for diffuse optical communication
"... In this paper, we have presented the original results of a comparative analysis of different types of coaxial excitation of the TM 01l mode in a cylindrical cavity containing a spherical lossy load (a fruit) and considered various factors influencing on the efficiency of coupling and the patterns o ..."

systems are not typically employed due to received signal-power limitations, alignment issues, and low data rates, we propose the use of multiple input, multiple output (MIMO) signal-processing techniques to overcome these limitations and enable high-performance diffuse optical links. Using IR light
Channel Knowledge Acquisition in Relay and Multi-Point to Multi-Point Transmission Systems
, 2013
"... Most of the relaying strategies exploit channel state information (CSI), but there exist only a few limited works on acquisition of the required CSI. In this paper we present general protocols and pilot designs for CSI acquisition in different types of relay systems using multiple-input multiple-ou ..."
