Texto completo da fonteThe high increase of bandwidth greedy applications in recent years, and the global wireless bandwidth shortage in the traditional low band spectra has made vacant spectrum in millimeter-wave (mmWave) frequency bands of a paramount importance for all key players in the cellular industry. This being said, wireless communications over mmWave frequencies will nevertheless be a challenging task, mainly due to the poor reflectivity, high absorption and large free space propagation losses on such high bands.One of the very popular solutions to overcome the aforementioned propagation issues is to use massive antenna arrays, a technique that is made possible because if the proportionality between the array's physical size and the carrier wavelength (mmWave frequencies are characterized by small wavelength, which translates to compact antenna arrays with high number of elements). However, the high cost, power consumption and complexity of the mixed signal hardware at mmWave make having large antenna arrays with digitally controlled elements infeasible.The partitioning of the signal processing operations related to the mmWave transceivers made having a cost and energy effective implementation of these latter possible. These novel architectures are known as hybrid analog/digital beamforming transceivers. These hybrid architectures divide the precoding/combining processing between the analog and digital domains, which reduces considerably the required number of RF chains.Hybrid array structures entail nevertheless their own challenges, the low signal-to-noise ration (SNR) resulting from high propagation losses, the large dimensionality of the Multiple-Input-Multiple-Output (MIMO) wireless channel matrix and the presence of analog processing complicate the acquisition of the channel state information (CSI) and the computation of the MIMO precoders and combiners.Addressing the aforementioned challenges is key to enabling mmWave based cellular. With this motivation in mind, this dissertation proposes novel algorithmic solutions that tackle them. We propose fast and low complexity solutions that yield efficient performance while respecting the hardware constraints. The main contributions of the present thesis consist of devising fast and low complexity algorithms that enable building robust precoders and combiners during the beam training phase and without the need of explicitly estimating the CSI and then using it to derive these beamformers

Millimeter-wave (mmWave) has become one of the most promising technologies to deal with the growing demand for data transmission over wireless networks. Due to the propagation characteristics in the mmWave band, there is a higher path loss compared to the microwave frequency band. MmWave communication combined with massive MIMO technique has been proposed. In traditional multi-user fully-digital MIMO system, every antenna connects to one RF chain. Unfortunately, due to the hardware cost and power constraint, fully-digital architecture with a large antenna array in millimeter-wave systems is difficult to implement. Recent works in the literature advocate a hybrid architecture for millimeter-wave systems to solve this problem. In this thesis, after reviewing the recent literature, we proposed new multiuser hybrid transeiver architecture and algorithms in mmWave systems, and then proposed two designs to harvest array gain. Simulation results demonstrate that our proposed algorithms can approach to the total transmission rate of the fully-digital architecture.
