Uniform Quantization for Multi-Antenna Amplify–Quantize–Forward Relay
In this paper, we investigate a multi-antenna amplify-quantize–forward (AQF) relay system, where a half-duplex relay quantizes both the real and imaginary components of amplified received signals, storing them in memory before forwarding them to a

Investigation of MIMO Channel Characteristics in a Two-Section Tunnel at 1.4725 GHz
This paper presents results from a wide band single-input–single-output (SISO) and 16 × 16 virtual multiple-input–multiple-output (MIMO) measurement campaign at a center frequency of 1.4725 GHz in a 100-meter long tunnel laboratory which is terminated by

Adaptive widely linear processing for MIMO systems
Wireless communication systems using two or more transmit antennas and one or more receiving antennas have emerged in recent years. There are several reasons for this to be occurring, including: the increasing demand for high data rate, high user ...

Sparse Grassmannian Design for Noncoherent Codes via Schubert Cell Decomposition
In this paper, we propose a method for designing sparse Grassmannian codes for noncoherent multiple-input multiple-output systems. Conventional pairwise error probability formulations under uncorrelated Rayleigh fading channels fail to account for rank ...

Phase Noise Effects in Synchronized Wireless Networks for MIMO-OFDM [PDF]
Channel impairments effects are evaluated by inclusion of phase noise in a synchronization error correction algorithm for MIMO (Multiple Input Multiple Output) OFDM (Orthogonal Frequency Division Multiplexing) systems.

Wideband analysis of indoor MIMO channels [PDF]
The application of MIMO communication systems in real environments will invariably require systems to operate over wideband channels. Although suitable techniques for processing wideband MIMO channels have been reported, their evaluation has mainly been ...

Robust stability and performance analysis for multiple model adaptive controllers
—For an Estimation Based Multiple Model Switched Adaptive Control (EMMSAC) algorithm controlling a MIMO minimal LTI plant, $l_p,\ 1\le p\le \infty$ bounds on the gain from the input and output disturbances to the internal signals are obtained which are ...

A universal space-time architecture for multiple-antenna aided systems
In this tutorial, we first review the family of conventional multiple-antenna techniques, and then we provide a general overview of the recent concept of the powerful Multiple-Input Multiple-Output (MIMO) family based on a universal Space-Time Shift ...
