A novel random access scheme for M2M communication in crowded asynchronous massive MIMO systems
Huimei Han, Wenchao Zhai, Zhefu Wu +3
A new random access scheme is proposed to solve the intra-cell pilot collision for M2M communication in crowded asynchronous massive multiple-input multiple-output (MIMO) systems.…
