… 2) We propose a SCNet for downlink CSI prediction in FDD massive MIMO systems, which
is applicable to complex-valued function approximation with complexvalued representations. …

… In this article, we formulate the downlink channel prediction for FDD massive MIMO systems
as a DTL problem, where each learning task aims to predict the downlink CSI from the …

… (cell-free) massive MIMO systems and for both TDD and FDD system operation modes, as
we will discuss in Section IV. Channel Model: Let hu,m(f1) denote the channel from user u to …

… We consider adopting an OFDM model in FDD massive MIMO systems. The BS is equipped
with Nb antennas, the UE is equipped with Nu antennas, and the number of subcarriers is Ns…

… the DL channel estimation process using DTS in an FDD MaMi system with a colored noise
environment. In particular, the CSI estimation process is conditioned on the received training …

… estimation for all users is performed at the base station based on the matrix completion [25],
based on which the overhead of downlink channel training as well as uplink channel …

… We show that with such a training sequence, the parameters of DL MIMO channels can be
provably identified even when the number of paths largely exceeds the number of received …

… CHANNEL MODEL We consider a FDD massive MIMO scenario where each user has a
single-antenna and transmits an UL training sequence that is orthogonal to those of the other …

… Channel Model and Conventional Approaches This paper considers an FDD massive
MIMO system operating in mmWave propagation environment [9] in which the number of …
