Joint Spatial Division and Multiplexing
, 2012 We propose Joint Spatial Division and Multiplexing (JSDM), an approach to multiuser MIMO downlink that exploits the structure of the correlation of the channel vectors in order to allow for a large number of antennas at the base station while requiring reduced-dimensional Channel State Information at the Transmitter (CSIT).

Joint transform correlator with spatial code division multiplexing
Applied Optics, 2006 A joint transform correlator may suffer from overlapping of the zero diffraction order of the output, which does not contain relevant information, and the correlation peaks that appear in the first diffraction orders if objects are not sufficiently separated. Such overlapping significantly reduces the signal-to-noise ratio of the identification process.

Investigation of Fan In and Fan Out Technologies for Multi Core Fiber
Guangtongxin yanjiu, 2021 Spatial division multiplexing based on the multi-core fiber has been believed as a promising and effective way to overcome the foreseeable capacity crunch of single mode fiber transmission. Fan-in Fan-out (FIFO) technology for multi-core fiber is the key

Phase-Noise Compensation for Spatial-Division Multiplexed Transmission [PDF]
Optical Fiber Communication Conference, 2017 The problem of correlated phase noise in spatial-division multiplexed transmission is studied. To compensate for the phase noise, an algorithm for joint-core phase-noise estimation and symbol detection is proposed, which outperforms conventional methods.

Molecular Oncology, EarlyView.We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...
