15.1 Introduction

This chapter is devoted to addressing millimeter-wave (mmWave) channels and providing an overview on signal processing problems for mmWave communication in 5G. In the mmWave band, where frequency bands are above 30 GHz, a large number of spectrums are potentially available. In so far as a 5G wireless communication systems should be able to provide much higher area traffic capacity – downlink traffic density of 750 Gbps/km² [1], with a peak data rate of up to 10∼100 Gbps – a mobile network based on mmWave band radio access technology (RAT) is a key component.

The unique characteristics of the mmWave channel and the requirements for mmWave communications in 5G impose new requirements on mmWave channel modeling. New channel-modeling approaches therefore need to be developed for mmWave communication in 5G. This chapter presents two channel-modeling approaches to meet the requirements for a 5G mmWave channel model: an enhanced 3GPP/SCM ...
