Performance analysis and comparison of optical signal processing beamforming networks: a survey

Forthcoming wireless systems are developed to support greater data rate and extra coverage area. This can be achieved
with the help of multiple input multiple output and smart antenna techniques. One of the major rapidly emerging areas of
communication is the smart antenna system which aids in attaining better coverage by increasing the signal strength only
in the chosen direction. With effective optical beamforming techniques, the smart antenna systems demonstrate to be more
competent in terms of excellence of signals in wireless communication. In this paper, a succinct outline of the smart antenna,
an analysis and the comparison of different architectures of optical signal processing beamforming network (OSPBFN) is
presented. The performance of OSPBFN is analyzed and the comparison is done for different architectures with the antenna
radiation parameters. This paper can enhance the understanding of the ongoing research work in the area of OSPBFN.
