1. Pilot Contamination and Mitigation Techniques in Massive MIMO Systems
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : A multi-antenna base station (BS) can spatially multiplex a few terminals over the same bandwidth, a technique known as multi-user, multiple-input multiple-output (MU-MIMO). A new idea in cellular MU-MIMO is the use of a large excess of BS antennas to serve several single-antenna terminals simultaneously. READ MORE

2. Receiver Design for Vehicular Communications
University essay from KTH/KommunikationsteoriAbstract : As the mobility of people increases, so does the density of vehicles on road networks. This comes at a cost, causing traffic congestions and raising the number of casualties. Wire- less communications between vehicles will enable the development of Intelligent Transport Systems (ITS), which are expected to assist and manage road transportation. READ MORE

3. Multiantenna Time Of Arrival Estimation
University essay from KTH/SignalbehandlingAbstract : In the communications literature exist many documents that explain how to use spatial diversity to improve the performance of the system. However, the use of spatial diversity has not been studied in depth for GNSS, although in the last years the subject has received some interest, [6] and [20]. READ MORE

4. Low Complexity Channel Estimation for OFDM Systems Based on LS and MMSE Estimators’
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : In this paper we investigate the block-type pilot channel estimation for orthogonal frequency-division multiplexing (OFDM) systems. The estimation is based on the minimum mean square error (MMSE) estimator and the least square (LS) estimator. We derive the MMSE and LS estimators’ architecture and investigate their performances.
