| Sumario: | ABSTRACT: In this thesis, we consider an analog antenna combining architecture for a MIMO wireless transceiver, while pointing out its advantages with respect to the traditional MIMO architectures. In the first part of this work, we focus on the transceiver design, especially the calculation of the beamformers that must be applied at the RF. This analysis is performed in an OFDM system under different assumptions on the channel state information. As a result, several criteria and algorithms for the selection of the beamformers are proposed. In the second part, we address the FPGA design and implementation of a baseband processor for this architecture. This baseband processor is based on the standard IEEE 802.11a. Finally, some real-time tests of the implemented baseband processor are carried out both in stand-alone configuration and also with the whole physical layer setup. |
