Bit-Interleaved Coded Multiple Beamforming in Millimeter-Wave Massive MIMO Systems

Abstract

An analysis of the diversity gain for bit-interleaved coded multiple beamforming (BICMB) method in millimeter-wave (mm-Wave) massive multiple-input multiple-output (MIMO) systems is carried out for both the single-user and multi-user scenario. We show that the diversity gain is independent of the number of data streams and full spatial multiplexing order can be achieved in both scenarios. Also, we show that the diversity gain in the multi-user scenario is independent of the number of users in the system and only depends on the number of the remote antenna units (RAUs) at the transmitter side,

Diversity Analysis of Millimeter-Wave OFDM Massive MIMO Systems

“…In a similar fashion to [8], [17], one can find the beamforming matrices at both the transmitter and the receiver sides. We first rewrite (1) in a more compact form, then by assuming that the number of antennas at both the transmitter and the receiver goes to infinity, we find the optimal solutions for the beamforming matrices [14].…”

“…There are some criteria which we need to consider when designing the interleaver. For the BICMB-OFDM system, the interleaver is designed such that [8], [15] 1) Consecutive coded bits are interleaved within one OFDM symbol.…”

“…In [8], we showed that by using bit-interleaved coded multiple beamforming (BICMB), one can achieve the maximum diversity gain mm-Wave massive MIMO system with a distributed antenna subarrays. Also, in [9], we used BICMB with perfect coding (BICMB-PC) to achieve the maximum diversity gain.…”

“…Also, in [9], we used BICMB with perfect coding (BICMB-PC) to achieve the maximum diversity gain. The diversity gain derived in [8], [9] is based on a flat-fading channel model. Also, the diversity gain is independent of the number of transmitted data streams and depends on the number of RAUs at both the transmitter and the receiver, the number of propagation paths, and the large-scale fading coefficient in each subchannel.…”

“…1547155. systems. To overcome this diversity degradation, in [11], we proved that by using BICMB in a single-user mm-wave massive MIMO system with distributed antenna-subarray architecture both full diversity gain and full multiplexing gain can be achieved. Furthermore, unlike [2], the diversity gain can be increased by increasing the number of remote antenna units (RAUs) at both the transmitter and the receiver side.…”
