In this paper we carry out the asymptotic diversity analysis for\nmillimeter-wave (mmWave) massive multiple-input multiple-output (MIMO) systems\nby using bit interleaved coded multiple beamforming (BICMB). First, a\nsingle-user mmWave system which employs Mt antenna subarrays at the\ntransmitter and Mr antenna subarrays at the receiver is studied. Each\nantenna subarray in the transmitter and the receiver has Nr and Nt\nantennas, respectively. We establish a theorem for the diversity gain when the\nnumber of antennas in each remote antenna unit (RAU) goes to infinity. Based on\nthe theorem, the distributed system with BICMB achieves full spatial\nmultiplexing of Lt=\∑i,jLij and full spatial diversity of\n frac\(\∑i,j\βij\)2\∑i,j\βij2Lij-1\nwhere Lij is the number of propagation paths and \βij is the large\nscale fading coefficient between the ith RAU in the transmitter and the jth\nRAU in the receiver. This result shows that one can increase the diversity gain\nin the system by increasing the number of RAUs. Simulation results show that,\nwhen the perfect channel state information assumption is satisfied, the use of\nBICMB increases the diversity gain in the system.\n
