In this paper, SC-FDMA and OFDM systems with fast tracking equalizer based on RLS algorithm in multipath fading environments are proposed. In the proposed SC-FDMA and OFDM system with fast tracking equalizer, known-reference signals are allocated to the 1st slot of transmitting slots on each subcarrier at the transmitter. The transmitted signals are equalized with the reference signals on the frequency...
In this paper, transmission performance for downlink MU-MIMO (Multiuser Multiple-Input Multiple-Output) systems with computer simulation and field experiment are described. The downlink MU-MIMO system is constructed as a transmitter with 6 antennas and receivers with 2 antennas, and the maximum number of users(receivers) is 3. In computer simulation, MU-MIMO transmission system can be realized by...
