Multiple-input multiple-output circular SAR

2014 15th International Radar Symposium (IRS), 2014
Interest on circular and multicircular SAR acquisitions has been increased in the past few years due to the inherent potentials they provide, e.g., full 3-D reconstruction and subwavelength resolution. However, one main limitation is the size of the spotlighted region, which is basically defined by the range ambiguities, the pulse repetition frequency (

Multiple Input-Multiple Output Quantum Radar

2020 IEEE Radar Conference (RadarConf20), 2020
We consider a quantum radar, using as sources for entangled photons devices with spontaneous parametric downconversion, with a given number of channels. This conception is similar to a MIMO radar and we exploit the detection theory for this case to show a neat improvement in the receiver operating characteristics (ROC) curves with increasing number of ...

Multiple Input Multiple Output (MIMO) Antennas

2023
The advancement of antennas that can access high data speeds, and have higher gain, is largely responsible for the advancements in wireless technology. One such antenna called the multiple input multiple output (MIMO). This antenna has attracted the utmost attention of the researchers owing to its features like higher capacity, increased data rate, low

Multiple-Input Multiple-Output SAR

2017
For the conventional SAR, the swath width and azimuth resolution are contradictions because of the limitations of minimum antenna area, so they cannot be improved simultaneously.

Identification of interconnected multiple-input multiple-output systems: Application to a multiple-input multiple-output thermal process

International Journal of Systems Science, 1999
A new algorithm for estimation of the parameters of multiple-input multiple-output (MIMO) systems with strong interconnections between inputs and outputs. The proposed algorithm uses a new transformation of the input-output difference equation. A modified Kalman filter is employed to estimate recursively and sequentially parameters of the MIMO system ...

Power permutation modulation in multiple‐input multiple‐output systems

Transactions on Emerging Telecommunications Technologies, 2021
AbstractThe forthcoming communications standards are conjectured to require unprecedentedly high spectral efficiency values. Motivated by this fact, we propose a new transmission scheme for multiple‐input multiple‐output systems, which is termed as power permutation modulation (PPM). In addition to the conventional data‐carrying modulated symbols, some

Linear receivers for the multiple-input multiple-output multiple-access channel

IEEE Transactions on Communications, 2006
We consider a multiuser multiple-input multiple-output (MIMO) communication system using code-division multiple access (CDMA) and multiuser detection to discriminate the different users. Our focus is on the CDMA uplink of a frequency-nonselective Rayleigh fading channel.
