In this paper, we propose a novel codebook for multiple-input multiple-output (MIMO) Rician fading channels. While the most conventional codebooks are designed in Rayleigh fading channels, we design a hybrid codebook which combines discrete Fourier transform matrix-based codebook for MIMO Rayleigh fading channels and array matrix-based codebook for MIMO line-ofsight channels. Especially, a back...

This article presents a tutorial on multiuser multiple-antenna wireless systems with a very large number of antennas, known as massive multi-input multi-output (MIMO) systems. Signal processing challenges and future trends in the area of massive MIMO systems are presented and key application scenarios are detailed.

This paper addresses the joint design of transmit and receive antennas or linear processing for multicarrier MIMO channels under a variety of design criteria. Instead of considering each design criterion in a separate way, It is generalized that the existing results by developing an existing unified framework based on considering two families of objective functions that embraced most reasonable...

In this paper, we have investigated the application of non-binary LDPC codes to spatial multiplexing MIMO systems with a large number of low power antennas. We demonstrate that such large MIMO systems incorporating with low-complexity MMSE detector and non-binary LDPC codes can achieve low probability of bit error at near MIMO capacity. The new proposed non-binary LDPC coded system also perform...

Antenna (subset) selection techniques are feasible to reduce the hardware complexity of multiple-input multiple-output (MIMO) systems, while keeping the benefits of higher-order MIMO systems. Many studies of antenna selection schemes are based on frequency-flat channel models, which are inconsistent to broadband MIMO systems employing spatial-multiplexing. In broadband MIMO systems aiming to pr...

Wireless communications using Multiple-Input Multiple-Output (MIMO) links has emerged as one of the most significant breakthroughs in modern communications because of the huge capacity and reliability gains promised even in worst fading environment. This paper presents the optimized behaviour of MIMO systems over Rayleigh and Rician Fading channel environments. MIMO transmission systems are inv...

The Complete Complementary Sequence (CC-S) consists of several complementary orthogonal sequences and has optimal sidelobe level performance, which is satisfied with the requirement of the orthogonal Multiple Input Multiple Output (MIMO) radar signals. Aimed at the difficulty of high sidelobe level in Synthetic Aperture Radar (SAR) imaging processing in range dimension, an approach of depressin...

1. Introduction The multi-input multi-output (MIMO) technique incorporating space-time coding is a candidate for the next generation high performance wireless communication systems. The MIMO technique employs multiple-element antennas to establish spatial subchannels to improve spectrum efficiency. The promised increase in channel capacity by MIMO is possible only if rich-scattering is present ...
