The purpose of this paper is to experimentally study Optical All Pass Filters (OAPF) and optimize the value of distance of origin from poles (r). Using the value of transfer function of optical all pass filter which is of 2 order we found the factor of numerator and denominator. In this work, we took the value of ̳r‘ as 0.660 and the angular position (w0)(More)
RFID system (Radio Frequency Identification), an automatic identification system relying on exchange of information through radio frequency, is emerging as one of important technologies that find its use in various applications ranging from healthcare, construction, hospitality to transportation sector and many more. This paper describes about RFID(More)
With the utmost application of wireless network and internet has actuated substantial demands for information security and data concealment. However, wireless systems are more susceptible to illegitimate access and eavesdropping. RC5 has a variable parameters of word size, length of secret key and number of rounds. Ronald Rivest suggested the RC5 algorithm(More)
The ever increasing growth of users and network capacity makes the security of passive optical networks (PON) an issue of great concern. In this paper, we present a novel work to enhance the physical layer security for wavelength division multiplexing orthogonal frequency division multiplexing PON. Elliptic curve with Diffie–Helman key exchange protocol is(More)
Code division multiple access (CDMA) is a most promising technique for using channel efficiency. Multiple access interference (MAI) is a limiting factor for the capacity of CDMA system. Proposed design is based on the step by step practical implementation of matched filter (MF) detection and minimum mean squared error (MMSE) detection. Thus, providing(More)
