Query: Asymptotic Performance Analysis of GSVD-NOMA Systems with a Large-Scale
  Antenna Array   This paper considers a multiple-input multiple-output (MIMO) downlink
communication scenario with one base station and two users, where each user is
equipped with m antennas and the base station is equipped with n antennas. To
efficiently exploit the spectrum resources, we propose a transmission protocol
which combines generalized singular value decomposition (GSVD) and
non-orthogonal multiple access (NOMA). The average data rates achieved by the
two users are adopted as performance metrics for evaluation of the proposed
GSVD-NOMA scheme. In particular, we first characterize the limiting
distribution of the squared generalized singular values of the two users'
channel matrices for the asymptotic case where the numbers of transmit and
receive antennas approach infinity. Then, we calculate the normalized average
individual rates of the users in the considered asymptotic regime. Furthermore,
we extend the proposed GSVD-NOMA scheme to the MIMO downlink communication
scenario with more than two users by using a hybrid multiple access (MA)
approach, where the base station first divides the users into different groups,
then the proposed GSVD-NOMA scheme is implemented within each group, and
different groups are allocated with orthogonal bandwidth resources. Finally,
numerical results are provided to validate the effectiveness of the proposed
GSVD-NOMA protocol, and the accuracy of the developed analytical results.
