This brief presents a novel design of high-isolation dual-band antenna with a close distance
for 5G applications. The proposed antenna consists of two symmetrical monopole antenna …

The fifth-generation of mobile networks (5G) claims for a radio access network (RAN) update
in order to support the enormous incoming wireless data traffic. In this context, we …

In the areas of signal processing and communications, such as antenna-array beamforming,
adaptive filtering, multiuser and multiple-input-multiple-output (MIMO) detection, channel …

This brief mainly investigates energy efficiency (EE) and spectrum efficiency (SE) for the
uplink massive multiple-input-multiple-output orthogonal frequency-division multiplexing …

We propose a closed-loop multiple-input multiple-output orthogonal frequency-division
multiplexing (MIMO-OFDM) transmission scheme appropriate for the IEEE 802.22 wireless …

In this brief, we present the design and implementation results of a digital 120 Mb/s multiple-
input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) wireless …

In this paper, we propose a power-efficient configurable multiple-input-multiple-output
(MIMO) detector, supporting QPSK, 16-QAM, and 64-QAM with low complexity. The …

The space–time-block-code (STBC) multiple-input–multiple-output (MIMO) zero-padding
orthogonal frequency-division multiplexing (ZP-OFDM) has been widely investigated in …

An improved implementation of QR decomposition for MIMO-OFDM detection based on the
Givens rotation method is presented in this paper. The hardware of QR decomposition is …

Although the maximum-likelihood decision-feedback equalization (ML-DFE) detection
method for multi-input multi-output (MIMO) system leads to a good compromise between the …
