We have investigated the performance and reliability improvement of cooperative free-space optical (FSO) communication over single input single output (SISO) system in this paper. The bit error rate (BER) analysis with quadrature phase shift keying (QPSK), gamma–gamma channel model and pointing error has been demonstrated for SISO and cooperative system.(More)
In this paper, we present the performance analysis of spatially multiplexed Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) Free Space Optical Communication system over turbulence induced fading channels MIMO is used with OFDM to enhance the performance and the capacity of the FSO system. The use of spatial multiplexing(More)
The Augmented Data Vortex switch has been proposed in our earlier publications as a high capacity, high throughput, and low-latency all optical packet switched interconnection network for optical switching that can overcome major challenges of all optical packet switching [1, 2]. Recently there has been much analysis and comparison of optical multistage(More)
In wireless communication Free Space Optical (FSO) communication is an emerging technology to provide high bandwidth and high quality communication. In this work we have evaluated the capacity of the Free Space Optical communication system with Multiple Input Multiple Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) technique under strong(More)
The tremendous growth of the high speed Internet and data traffic has created an enormous demand for transmission bandwidth of dense wavelength division multiplexed (DWDM) optical communication systems. With the advancement of wideband fiber-optical amplifiers, DWDM optical transmission systems are capable of providing capacities in excess of hundreds of(More)
In this paper, we have given a detail procedure to determine all-possible paths for all source - destination pairs in the data vortex all optical switch, and the terminal pair reliability performance of the switch has been obtained, using a simple analytical method. The paths found can also have applications for the study of survivability and quality of(More)
Multistage interconnection networks are employed in data centres to interchange information between the processors and memory elements. Data Vortex (DV) is a multistage minimum logic network which can be used in data centres. DV satisfies the requirements of the interconnection networks such as scalability and throughput. However, the latency is on higher(More)
