Query: Joint Channel Estimation / Data Detection in MIMO-FBMC/OQAM Systems - A
  Tensor-Based Approach   Filter bank-based multicarrier (FBMC) systems are currently being considered
as a prevalent candidate for replacing the long established cyclic prefix
(CP)-based orthogonal frequency division multiplexing (CP-OFDM) in the physical
layer of next generation communications systems. In particular, FBMC/OQAM has
received increasing attention due to, among other features, its potential for
maximum spectral efficiency. It suffers, however, from an intrinsic
self-interference effect, which complicates signal processing tasks at the
receiver, including synchronization, channel estimation and equalization. In a
multiple-input multiple-output (MIMO) configuration, the multi-antenna
interference has also to be taken into account. (Semi-)blind FBMC/OQAM
receivers have been little studied so far and mainly for single-antenna
systems. The problem of joint channel estimation and data detection in a
MIMO-FBMC/OQAM system, given limited or no training information, is studied in
this paper through a tensor-based approach in the light of the success of such
techniques in OFDM applications. Simulation-based comparisons with CP-OFDM are
included, for realistic transmission models.
