Impact of Antenna Correlation on Full-Duplex Two-Way Massive MIMO Relaying Systems - 2018

ABSTRACT:

This Project investigates the impact of antenna correlation on full duplex massive multiple-input multiple-output (MIMO) 2-means relaying systems. To be general, all nodes within the system are equipped with multiple antennas and arbitrary antenna correlation is taken into account. Deterministic equivalent of the achievable sum-rate is 1st given, which enables the derivation of the asymptotic sum-rate when the quantity of relay antennas is large. The impact of antenna correlation on the asymptotic add-rate is then thoroughly analyzed. The results reveal that with a large number of relay antennas, the asymptotic total-rate is freelance of the antenna correlation at the relay's transmitter facet, however it's Schur-concave with respect to the eigenvalue vectors of the involved antenna correlation matrices at both the users' transceiver sides and the relay's receiver aspect. In other words, the antenna correlations at each the users' transceiver sides and the relay's receiver aspect have detrimental effects on the sum-rate. Moreover, the antenna correlation at the users is a lot of vital to the asymptotic sum-rate than that at the relay. The analysis is general and will be easily reduced to think about 0.5-duplex and/or one-way huge MIMO relaying systems. Numerical results are finally provided to validate the analysis. It is additionally shown that a larger number of user antennas might not continually lead to the next add-rate, and thus correct selection of the number of user antennas is necessary to maximise the total-rate.
