Most analytical work for zero-forcing (ZF) receivers are conducted for small-scale multiple-input multiple-output (MIMO) systems in large signal-to-noise ratio (SNR) region and under small channel estimation error conditions.

Proceedings of the IRE, 1944
After a discussion of the general problem of coupled antennas, the distribution of current in a center-loaded receiving antenna with its axis in the plane of a linearly polarized electric field is derived. Distribution curves are shown for a wide range of lengths, thicknesses, and load impedances.

Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference, 2010
Our aim is to develop a microwave receiver antenna system, which can form its radiation pattern (main lobe direction, null-point direction, structure of the side lobes), measure the direction of the RF source in milliseconds. In this paper we will show the theoretical background of the antenna system, the build-up of the realized system and some ...

Receiving antenna design for miniature receivers
IEEE Transactions on Antennas and Propagation, 1977A design procedure is described which determines the minimum required volume and the optimum dimensions for a ferrite loaded loop receiving antenna. The frequency of operation, bandwidth, transmitted signal strength, desired signal-to-noise ratio, receiver sensitivity, and the relative permeability of the ferrite are required to determine the design ...

Multi-Antenna FSR Receivers: Low Complexity, Non-Coherent, Massive Antenna Receivers
2018 IEEE Global Communications Conference (GLOBECOM), 2018Many 5G applications require low complexity transceivers that can exploit the benefits of massive antenna arrays while still maintaining low hardware, energy and computation costs. As a solution, this paper proposes a novel multi- antenna frequency shift reference (MA-FSR) receiver that uses only one down-conversion chain, supports single spatial ...

Planar Array of UWB Active Slot Antennas for Microwave Imaging of the Breast
IEEE Transactions on Antennas and Propagation, 2023A shielded planar array of active slot antennas is proposed for applications in the microwave imaging of the breast. The frequency band is from 3 to 8 GHz, where reflection loss better than 10 dB and interelement mutual coupling less than −20 dB are ...

Multi-antenna snapshot receiver
2019 European Navigation Conference (ENC), 2019A global navigation satellite system (GNSS) snap-shot receiver records a segment of data and then sends it to a server for processing. The server then sends information, regarding the position and time for the receiver, back. This technology enables low-power positioning and can also be used for remote processing of encrypted signals.

Plasma receiving dipole antenna
Bulletin of the Lebedev Physics Institute, 2010The possibility of signal reception (in a frequency range of 30–50 MHz) by the plasma dipole antenna excited by transmitter self-radiation in the same frequency range was experimentally shown.
