Linear Precoding for Downlink Network MIMO Systems
… of cell edge users. Beamforming, also known as linear precoding, is a possible transmission strategy to reduce the interference in such networks, and thereby improve spectrum utilization.In this thesis, we propose three novel clustered linear precoding schemes applicable to network MIMO systems …

Power allocation and linear precoding for wireless communications with finite-alphabet inputs
… practical communication system/networks through linear precoding and power allocation. First, the mutual information or capacity region is derived for finite-alphabet inputs such as phase-shift keying (PSK), pulse-amplitude modulation (PAM), and quadrature amplitude modulation (QAM) signals. This …

Flexible backhaul design with cooperative transmission in cellular interference networks
… zero-forcing beamforming schemes that require linear precoding over a single time/frequency slot (one-shot). Similar schemes are proposed which achieve a per user DoF greater than half with a minimal increase in the backhaul load. These results are derived for networks with intra-cell …

Advanced Interference Suppression Techniques for Spread Spectrum Systems
… number of bits. Symbol-based and block-based linear MMSE receivers are designed for detection. Fourthly, the proposed switched interleaving technique is further extended to multiple antenna multicarrier code-division multiple-access (MC-CDMA) systems. A new hybrid transmit processing technique …

Performance evaluation of massive MIMO Systems for future wireless access systems
… potential of massive MIMO through evaluation of linear precoding and receive combining methods that may be applicable to massive MIMO. Linear signal detection and precoding for MIMO is generally not optimal. Optimal methods such as Maximal Likelihood (ML) signal processing methods have high …

Doctoral Thesis: Massive MIMO in Real Propagation Environments
… exploiting the many spatial degrees of freedom, linear precoding/detection schemes can be used to achieve near-optimal performance. The large number of antennas also brings the advantage of large array gain, resulting in an increase in received signal strength. Better coverage is thus achieved. …

Iterative Leakage-Based Precoding for Multiuser-MIMO Systems
… the application of an iterative leakage-based precoding algorithm to practical multiuser-MIMO systems. We consider the effect of practical impairments including imperfect channel state information, transmit antenna correlation, and time-varying channels. Solutions are derived which improve …
