A comprehensive study is presented to assess the performance limitations of an optical multicore fiber (MCF) communication system due to crosstalk with on-off Keying (OOK) modulation scheme. The expressions of the signal power at the output of the different cores of the MCF with excitation to any one of the cores is found out along with the crosstalk due to coupling among the cores. Finally, the expression...
In this paper, we have presented our study on the use of nano-scale grating coupling structure to excite Surface Plasmon Polariton (SPP) for biosensing, which, despite its comparatively less popular implementation in this field holds substantial potential for improvement. We have used Gold as the noble metal to generate and optimize the resonance between plasmons and electromagnetic wave. We have...
An analytical approach is presented to evaluate the effect of cross-polarization in a polarization diversity MIMO satellite to ground link. Analysis is developed to found the interference due to cross-polarization in a 2 ∗ 2 MIMO satellite link. The expression of signal to interference plus noise ration (SINR) is developed. The Bit-Error-Rates(BER) performance results are evaluated for different environments...
Due to the presence of mutual coupling between antenna arrays and antenna steering angle mismatch, the performance of adaptive antenna array processor is degraded highly. For this reason, robustness of the adaptive antenna array processor has become an important issue. The main drawback of conventional loading is so as to there is no clear concept to select loading level according to errors. This...
Next-generation cellular standard will use millimeter wave (mmWave) frequencies to provide higher throughput. The base station will use massive array antenna to ensure better transmission to multiple users. We propose a power and an adaptive beamforming algorithm based on Counter Propagation Artificial Neural Networks (CP-ANNs). The hidden layer is a Kohonen network which categorizes the input pattern...
Analytical approach is presented to evaluate the effect of weak atmospheric turbulence on the bit error rate (BER) performance of an optical code division multiple access (OCDMA) free space optical (FSO) link using optical domain encoder and Sequence Inverse Keying (SIK) balanced photodetector receiver. The analysis is carried out to find the expression of the signal current and multi access interference...
To accommodate big data, new technologies and features have started to be used in core network. Consequently, optical transport network has evolved towards Elastic Optical Network (EON). Despite the effort made towards efficient and reliable network management, interoperability problem in multi-vendor setting of the EON remains unsolved and it hinders the network management and monitoring. Hence,...
Cardinality estimation is a major concern for proper network operation and maintenance. Cardinality estimation of a network can be performed using protocol based techniques. But, underwater environment makes these protocol based methods inefficient in underwater network. To solve this problem, underwater network cardinality has been estimated using cross-correlation of the received Gaussian signals...
In silicon photonics, due to the increasing complexity of the device designs and the increasing density of the functions integrated on a single circuit, the precise characterization of the building blocks has become essential in order to assess the quality of the fabrication outcomes. As waveguides are the fundamental building block of photonic integrated circuits, its accurate characterization is...
