Abstract
This chapter introduces the massive hybrid array architecture, where antenna elements are grouped into multiple analog subarrays, and a single digital signal is received from or sent to each subarray. It provides an affordable and spatially feasible solution for millimeter-wave (mmWave) massive array, and can achieve comparable performance with a full digital array thanks to the temporal and spatial sparsity of mmWave propagation channels. This chapter starts by presenting the hybrid array architecture, highlighting two typical configurations ...
