Description: the effects of neural
network aided estimation in such receivers are considered. Neural
network acts as a pre-processing block to the estimator.-Orthogonal frequency division multiplexing (OFDM) has
high data rate capacity and lower Inter Symbol Interference (ISI)
and is considered as the best solution for next generation mobile
communication. Multiple Inputs and Multiple Output (MIMO)
antenna system improve reception through spatial diversity and
high end coding. Combining these two, offers high interference
mitigation in wireless receivers. In this paper, the effects of neural

Description: Thanks to the small wavelength at millimeter
wave (mmWave) frequency, it is promising to combine massive
multiple-input and multiple-output (MIMO) with mmWave.
MmWave massive MIMO will differ the conventional
massive MIMO, due to the differences in propagation and
hardware constraints. This paper proposes a stochastic geometry
framework for uating the performance in large-scale
mmWave massive MIMO networks. Based on the system model,
analytical expressions are provided for the asymptotic signal-tointerference-
plus-noise ratio (SINR) distributions in both uplink
and downlink, when the number of base station antennas goes
to infinity. Numerical results indicate a fast convergence in the
SINR distribution to its asymptotic equivalence in dense mmWave
networks. A comparison with conventional massive MIMO shows
that mmWave massive MIMO achieves a higher cell throughput
with sufficiently dense deployments.-Thanks to the small wavelength at millimeter

Description: We present a novel beamforming technique
for multi-user frequency-selective indoor channels called
interference-nulling time-reversal (INTR). The beamformer is
implemented with a pre-filter designed to minimize the interuser
interference present in conventional time-reversal (TR).
Moreover, our technique relies on a large number of antennas at
the transmitter to mitigate inter-symbol interference, enabling
low computational complexity receivers. We demonstrate that
INTR outperforms previous TR techniques with respect to
average bit error rate per user and achievable sum rate. Thus,
INTR can be used for space division multiple access in no-Iine-ofsight
mm-wave massive MIMO, providing remarkable diversity
and multiplexing gains.

Description: OFDM技术基本能远离，国外一所大学教授基于MIMO技术讲座的ppt-MIMO systems can exploit multipath components to a certain extent, that is, MIMO can resist multipath fading, but for frequency selective deep fading, the MIMO system is still powerless. At present, the solution to frequency selective fading in MIMO systems is to utilize equalization technology, and another is to use OFDM. Most researchers think that OFDM technology is the core technology of 4G, 4G requires high spectrum utilization of OFDM technology, and improve the spectrum utilization effect is limited, the development of space resources reasonably on the basis of OFDM, which is MIMO+OFDM, can provide higher data transfer rate.

Description: In this paper, we employ iteratively decodable codes in a turbolike receiver of a multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) communication system. With such a receiver, we compare the decoding complexity and performance of a turbo code with a lowdensity-parity-check (LDPC) code.
