Massive multiple-input multiple-output (MIMO) is still valid as an important system to
increase performance of fifth generation (5G) and beyond wireless communication …

In this paper, we propose a novel pilot power allocation method that focuses on the
maximization of the energy efficiency. The core algorithm of this method, which is a dynamic …

Recent research results on multiple antennas system namely the multiple input multiple
output (MIMO) system show that huge potential be it the spectral efficiency or the …

In this paper, we consider multiple-input-multiple-output (MIMO) systems based on
multichannel beamforming (MB). We first consider capacity of the wireless communication …

In this study the authors provide a cross-layer design of multiple-input-multiple-output
(MIMO) systems, with the aim to maximize spectral efficiency. We consider MIMO systems …

The ability to provide high data rate is a key measure in 3GPP long term evolution (LTE).
Multiple input multiple output (MIMO) has emerged as an technique that increases the data …

We address design of optimal MIMO precoders/decoders in the minimum mean square error
(MMSE) sense. Prior work assumes full and perfect channel state information (CSI) at the …

In this paper, a new amplification scheme for adaptive MIMO systems is proposed and
tested. In this 'hybrid amplification'configuration, different amplifiers with different peak …

Link adaptation by adaptive modulation and power allocation in a V-BLAST system is
considered. The conventional detection order of the ZF-SIC (zero forcing based successive …

Subject of this paper is analysis of level crossing rate and average fading duration in
orthogonal subchannels of MIMO channel. For Rayleigh propagation, the exact analytical …
