Abstract

The recently implemented 4G network meets nowadays the necessities of a world in a continuous development. Among the new technologies introduced by this standard is the one in which multiple antennas are used at the receiver and at the transmitter ends (MIMO) in order to increase the overall system performances. Massive MIMO is an evolved version of the conventional MIMO that uses a significantly larger number of antennas at the transmitter / receiver. This technology will be included in the much-discussed 5G standard. Another technology that is present in 4G/5G standards is the orthogonal frequency-division multiplexing (OFDM), which is a modulation technique where the information is arranged in blocks of information symbols that are transmitted in parallel on orthogonal subcarriers, as well as new low complexity / high performances encoding techniques. In order to study the enhancement brought by these technologies, in this paper, we propose an uplink Massive MU-MIMO OFDM-based system with low-density parity-check (LDPC) coding used by multiple users which are active simultaneously, when the number of Base Station (BS) antennas varies from 10 to 100. Based on this proposed structure, the transmitter, receiver and communication channel will be simulated in Matlab/Simulink. Extensive Monte Carlo simulation are under development to evaluate the system performances in terms of Bit Error Rate (BER) as a function of Signal to Noise Ratio (SNR).
