摘要：

In order to enlarge the communication capability, a model of the multiplexing communication system with non-coherent vortex beams is established. One detector for measurement the signal of the vortex beam with topological charge of 0, which is a Gaussian beam, is located in the center of the cross sectional plane of vortex beam. The other three detectors are set around the first detector in the same plane to receive the power of the vortex beam with topological charge of 1. The principle of determining the emitting power of vortex beams, the radii and the positions of the detectors are suggested to increase the signals and reduce the interchannel crosstalk noise at the detectors. The signal powers as well as the interchannel crosstalk noise in a receiver channel are identical to that in another channel, respectively. This research may have applications in free space optical communications. (C) 2016 Elsevier B.V. All rights reserved.
