This paper presents the design of a metamaterial inspired symmetrical slotted patch antenna for triband operation with center frequency 2.5 GHz. antenna is designed. The outer dimensions of the patch are designed such that the antenna resonates at the upper resonant frequency. In addition, the dimensions of the slots are designed to control the lower(More)
Digital video watermarking has drawn the attention towards authentication and proof of ownership. Uncompressed domain watermarking has flourished over the years and related algorithms have been implemented on the software platform. Software watermarking algorithms work offline where videos are captured through device and embedding algorithms run on a PC(More)
Watermarking is the process of hiding a predefined pattern or logo into multimedia like image, audio or video in a way that quality and imperceptibility of media is preserved. Predefined pattern or logo represents the identification of the author. In recent years, rapid growth in digital multimedia has been noticed. Digital videos are widely exchanged on(More)
FSO (free space optical communication) is less costly and use frequency spectrum which is license free. In this paper, to send the electrical signal in the form of optical signal and reconstruct it in electrical signal we will use coherent detection technique. We also used OFDM techniques, which mitigate the consequence of frequency selected fading and the(More)
The conventional microstrip patch antenna (MSA) have low gain and low directivity. This paper presents coaxial feed rectangular microstrip patch antenna along with left-handed metamaterial (LHM) cover. The Proposed metamaterial cover increases the gain and directivity of the antenna in comparison to conventional microstrip patch antenna alone. The antenna(More)
H.264 is the advance video coding standard for the compression and distribution of a video content. It has larger complexity in order to satisfy the demand of high quality video at low bit rate. Moreover, it requires the effective implementation of all its internal blocks. In the paper, we focuses on the implementation of two important blocks for H.264(More)
Transformation is one of the fundamental blocks of many signal processing applications. The Hadamard transform is useful in variety of application including data encryption methods and latest data compression algorithms such as JPEG extended range (JPEG XR), High Efficiency Video Coding (HEVC) etc. Hadamard transform is multiplier less technique and(More)
