Single Input Multiple Output techniques for
Currently, there are three broadband :LUHOHVVV/RFDOO$UHD1HWZRUNV (WLAN) standards harmonised at the physical layer (based on OFDM) that operate in the 5 GHz band, i.e. ETSI BRAN HL/2 in Europe, IEEE 802.11a in the USA and ARIB MMAC HiSWAN in Japan. This paper focuses on the use of adaptive antennas for HL/2 [ETSI00]. The system shall be adapted to work in different propagation and interference ...
متن کاملMultiple Fuzzy Regression Model for Fuzzy Input-Output Data
A novel approach to the problem of regression modeling for fuzzy input-output data is introduced.In order to estimate the parameters of the model, a distance on the space of interval-valued quantities is employed.By minimizing the sum of squared errors, a class of regression models is derived based on the interval-valued data obtained from the $alpha$-level sets of fuzzy input-output data.Then,...
متن کاملCapacity Results on Multiple-Input Single-Output Wireless Optical Channels
This paper derives upper and lower bounds on the capacity of the multipleinput single-output free-space optical intensity channel with signal-independent additive Gaussian noise subject to both an average-intensity and a peak-intensity constraint. In the limit where the signal-to-noise ratio (SNR) tends to infinity, the asymptotic capacity is specified, while in the limit where the SNR tends to...
متن کاملThree-Dimensional Terahertz Coded-Aperture Imaging Based on Single Input Multiple Output Technology
As a promising radar imaging technique, terahertz coded-aperture imaging (TCAI) can achieve high-resolution, forward-looking, and staring imaging by producing spatiotemporal independent signals with coded apertures. In this paper, we propose a three-dimensional (3D) TCAI architecture based on single input multiple output (SIMO) technology, which can reduce the coding and sampling times sharply....
متن کاملDesign of Single Input Multiple Output DC-DC Converter
This paper proposes a design of single input multiple output (SIMO) dc–dc converter. The proposed converter can generate the voltage of a low voltage input to controllable levels of boosted output voltage and it can also produce the inverted output voltage. This dc-dc converter utilizes the properties of voltage clamping and soft switching based on a coupled inductor. In this paper, the design ...
