In this paper, we propose a reduced complexity and power efficient System-on-Chip (SoC) architecture for adaptive interference suppression in CDMA systems. The adaptive Parallel-ResidueCompensation architecture leads to significant performance gain over the conventional interference cancellation algorithms. The multi-code commonality is explored to avoid the direct Interference Cancellation (IC...

In this paper we study the strength of two hash functions which are based on Generalized Feistels. We describe a new kind of attack based on a cancellation property in the round function. This new technique allows to efficiently use the degrees of freedom available to attack a hash function. Using the cancellation property, we can avoid the non-linear parts of the round function, at the expense...

the condition within the contract is a principle that has been recognized in the islamic law but there is disagreement among the authorities concerning its impact on the condition of the contract in the two stages of formation and continuation of the contract. in the formation stage, the difference is in terms of the relation between the condition and the subject, concerning which, from among t...

This article is an attempt to survey the contraction and cancellation of the Reuter’s agreement as a one-sided approach and from special perspective, by using minimalistic ideology and with emphasis on multi-sided and various reasons and factors effective in the process of this contract.  On the basis of this research, in this contraction, different factors came together and augmented one anoth...

This review focuses on howling and entrainment artifacts in digital hearing aids. The howling may occur (especially at high gains), essentially due to the close proximity of the input microphone and the output loudspeaker. The entrainment, on the other hand, occurs when the input to the hearing aids is periodic, for example, music signals or alarm signals with strong tonal characteristics. We g...

Near-far resistant data detectors for frequency selective fading channels are proposed for the uplink of code-division multiple-access (CDMA) mobile communication systems. Parallel interference cancellation (PIC) is used to suppress the multiple-access interference (MAI) in the receiver. In order to improve the MAI estimates, the multistage principle is used. In this paper, three main issues ha...

A practical measure to estimate the immunity of block ciphers against differential and linear attacks consists of finding the minimum number of active S-Boxes, or a lower bound for this minimum number. The evaluation result of lower bounds of differentially active S-boxes of AES, Camellia (without FL/FL−1) and Feistel ciphers with an MDS based matrix of branch number 9, showed that the percenta...

Submit Manuscript | http://medcraveonline.com 43 amino acids. The PPP is derived from the Amyloid Precursor Protein (APP), which is “cut or cleaved by beta secretase and gamma secretase” to yield Aβ. Furthermore, the Aβ molecules can aggregate to form flexible soluble pathogenic Oligomers (https://www.ncbi.nlm.nih.gov/pmc/ articles/PMC4598734/). The Oligomers are toxic to nerve cells with multi...

Members of a multi-robot team, operating within close quarters, need to avoid crashing into each other. Simple collision avoidance methods can be used to prevent such collisions, typically by computing the distance to other robots and stopping, perhaps moving away, when this distance falls below a fixed threshold. While a simple method like this may skirt disaster, the results may be inefficien...
