The purpose of this dissertation is to study and evaluate the performance of a
MU-MIMO system, in order to identify the advantages that this groundbreaking
technology can offer.
This dissertation presents a Monte Carlo simulation, that generates a random
channel matrix for both uplink and downlink of a MU-MIMO system.The
receivers used for this simulation were MRC/MRT .The modulation scheme for
downlink is OFDM, and for uplink SC-FDMA. Pilot signals are simulated as
Zadoff Chu orthogonal sequences.
This simulation uses the optial values for the power, the number of users and
the number of of pilot symbols, based on the given whole numbers for the base
station antennas and the cohorence interval .Besides guard intervla and channel
estimation techniche, the rest system takes in account LTE standards. For the
simulation implementation, MATALB R2013a was used.
