<p>The strength of the attenuated received signal and the 3D path loss in mmWave transmission are shown. To enhance spectral efficiency and transmission latency a CP-less OCDM system and to reduce both out-of-band (OOB) spectrum power and consumption of additional resources due to cyclic prefixing a proper subcarrier mapping is proposed.</p>
<p>For achieving negligible BER and increased channel capacity a QR decomposition and Gram Schmidt orthogonalization (QR-GSO)-based multi-user, multiple-input, multiple-output (MU-MIMO) precoding system is also proposed in this paper.</p>

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
