Abstract

Millimeter wave (mm-Wave) technology utilizes massive multiple-input multiple-output (MIMO) as these are key approaches to meet massive data rate requirements for future wireless communication. Including a 64-DAPSK modulation scheme along with an OFDM multicarrier approach can be an applicable approach to further decrease the complexity of HF communication systems. However, the higher bit error rate was still a matter of concern. Therefore, this paper discusses the significant loss of diffracted beams caused by free-space path loss at 7 GHz bands. The first approach was millimeter-wave modulating with a 64DAPSK-OFDM technique using multi‐beam, such as the 5G, to reach high-gain antennas for both ends of the link. The second approach to mitigate path loss is to deploy many-element phased arrays forming MIMO links with users. Therefore, simulation results showed the effectiveness of the two approaches, mainly the second approach, which can be achieved by adaptive beam steering in demanding mobile high-gain antenna scenarios.
