This paper comments the work performed to implement the basic features of a Cyclic Prefix-Coded Orthogonal Frequency Division Multiplexing (CP-COFDM) based wireless communications system, operating in the 28 GHz 5G-mmWave band, and to evaluate its behavior for Urban Micro cells (UMi) environments and typical Line Of Sight/ Non Line Of Sight (LOS/NLOS) scenarios. Simulations are implemented on Simulink using Communications and DSP toolboxes available on MATLAB ®. Realistic mmWave channels are achieved using reference models derived from intensive simulations on NYUSIM. From these models, the main propagation parameters are extracted and the system is adjusted to ensure effective communications by avoiding multipath related problems, such as Inter-Symbol Interference (ISI) and Inter-Channel Interference (ICI). This system uses Orthogonal Frequency Division Multiplexing (OFDM), QPSK and 8-PSK modulations, Reed-Solomon (RS) channel coding and two different schemes for pilots insertion whose performance in terms of Bit Error Rate (BER) and spectral efficiency is evaluated.
