In the present days, for the human body anatomical study and for the treatment planning medical science very much depend on the medical imaging technology and medical images. Specifically for the human brain, MRI and CT widely prefers and using for the imaging. But by nature medical images are complex and noisy. This leads to the necessity of processes that reduces difficulties in analysis and improves...
Orthogonal frequency division multiplexing (OFDM) may be united with antenna arrays at the transmitter and receiver side to improve the diversity gain and to improve the system competence on time-variant along with the frequency-selective channels, which results in a multiple-input multiple-output (MIMO) composition. The space-time block coding (STBC) incorporated for OFDM systems with multiple transmit...
In the recent years Mobile Ad-hoc Network is emerging as a very popular technology in the wireless network. Because of its dynamic topology and its infrastructure less architecture, it is vulnerable to various types of attack. Providing security against the intruder is a challenging task in MANET. In this paper, we present the Modified Enhanced Adaptive Acknowledgment (EAACK) based Intrusion Detection...
There are different ways to protect medical images, most commonly used are steganography, watermarking, encryption etc. Due to the advantages of watermarking it has achieved a great importance in the field of image security. This paper gives a comparative analysis on applying SVD on different sub bands of a Haar wavelet transformed medical image. The experimentation is done using MRI and CT scan medical...
The greatest favour of MIMO systems is that more satisfactory performance can be easily achieved without using additional transmit power or extension of the bandwidth. However, its main disadvantage is that additionally high-cost radio frequency (RF) modules are an essential necessity as multiple antennas are deployed. In general, RF modules include components like low noise amplifier (LNA), frequency...
