Abstract In the field of video protection, selective encryption (SE) is a scheme which ensures the visual security of a video by encrypting only a small part of the data. This paper presents a new SE algorithm for H.264/AVC videos in context-adaptive variable-length coding mode. This algorithm controls the amount of encrypted alternative coefficients (ACs) of the integer transform in the entropic encoder.

Compact notch loaded half disk patch antenna for dualband operation

Ashish Singh, Jamshed Aslam Ansari, Kumari Kamakshi, Anurag Mishra and Mohammad Aneesh
University of Allahabad, India

Abstract In this article, microstrip patch antenna loaded with two symmetrical vertical notches and shorting pin is investigated for dualband operation using circuit theory concept based on modal expansion cavity model. It is found that the antenna resonates at 2.84 and 6.33 GHz for upper and lower resonance frequencies respectively. The bandwidth of the compact notch loaded antenna at lower resonance frequency is 9.94 % (theoretical) and 6.67 % (simulated) whereas at upper resonance frequency, it is 12.99 % (theoretical) and 11.59 % (simulated).» Read the summary

Improved method for searching interleavers from a certain set using Garello’s method with applications for the LTE standard

Lucian Trifina, Daniela Tarniceriu
Technical Iniversity Gh. Asachi, Iasi, Romania

Abstract In this paper, we propose a method for searching interleavers within a certain class, with the aim of designing turbo codes with good distance spectrum. The method is based on a modified version of Garello’s algorithm and consists in the calculation of frame error rate truncated upper bound. Here, it is applied to quadratic permutation polynomial (QPP) interleavers able to outperform those chosen for the long-term evolution (LTE) standard, for lengths up to 1,504 bits.» Read the summary
