The bulk of the research on long term evolution/long evolution-advanced [(LTE)/(LTE-A)] packet scheduling is concentrated in downlink and uplink comparatively less explored. In uplink, channel aware with throughput maximization has been widely studied while considering an infinitely backlogged buffer model, which makes investigations unrealistic. Therefore, we propose optimal procedure realisti...

In this paper, an algorithm of the median-cut quantization (MCQ) is proposed. MCQ is the technique that reduces multi-valued samples to binary-valued ones by adaptively taking the median value as the threshold. In this work, the search process of the median value is derived from the quick-sort algorithm. The proposed algorithm searches the median value bit by bit, and samples are quantized duri...

In this paper, we propose an algorithm called Optimum Intensity Based Distributed Hiding (OIBDH) for secret data hiding inside cover images. The algorithm is a modified version of Bit Plane Splicing LSB technique with better hidden capacity and improved embedding process. The proposed algorithm outperforms Bit Plane Splicing LSB technique as more data can be hidden without degrading the quality...

Received Nov 21, 2017 Revised Jan 26, 2018 Accepted Feb 12, 2018 In the OFDM communication system channel encoder and decoder is the part of the architecture. OFDM channel is mostly affected by Additive White Gaussian Noise (AWGN) in which bit flipping of original information leads to fault transmission in the channel. To overcome this problem by using hamming code for error detection and corre...

Lossless compression schemes with secure transmission play a key role in telemedicine applications that helps in accurate diagnosis and research. Traditional cryptographic algorithms for data security are not fast enough to process vast amount of data. Hence a novel Secured lossless compression approach proposed in this paper is based on reversible integer wavelet transform, EZW algorithm, new ...

This paper gives a new definition of general weighted (GW) fairness and shows how this can achieve various fairness definitions, such as those mentioned in the ATM Forum TM 4.0 specifications. The GW fairness can be achieved by calculating the ExcessFairshare (weighted fairshare of the left over bandwidth) for each VC. We show how a switch algorithm can be modified to support the GW fairness by...

A novel test-per-clock built-in self-test (BIST) equipment design method for combinational or full-scan sequential circuits is proposed in this paper. Particularly, the test pattern generator is being designed. The method is based on similar principles as are well known test pattern generator design methods, like bit-fixing and bit-flipping. The novelty comprises in proposing a brand new algori...

A set of n weighted points in general position in Rd defines a unique regular triangulation. This paper proves that if the points are added one by one, then flipping in a topological order will succeed in constructing this triangulation. If, in addition, the points are added in a random sequence and the history of the flips is used for locating the next point, then the algorithm takes expected ...

There has been significant interest in free-space optical (FSO) communication by the research community recent years. This is due to its high data rate, unlicensed spectrum, low cost, and immense security for FSO systems. Due these advantages, can have broader applications that extend from terrestrial satellite communication. Atmospheric turbulence (AT) induced fading a primary problem link sin...
