657 Abstract— Differential detection algorithm for DBO-CSS based on maximum signal energy detection (MSED) using viterbi algorithm is proposed. In order to mitigate SNR degradation caused by differential decoding, a modified viterbi algorithm with so called correlation metric (CM) in every state is proposed. It is shown that the performance gain of the proposed algorithm when compared with that...

In this thesis, we revisit differential and non–coherent transmission techniques over fading channels. In particular, we consider receiver design for differential space–time modulation (DSTM) over correlated multiple–input multiple– output (MIMO) fading channels and the performance analysis of differential phase shift keying (DPSK) and non–coherent frequency shift keying (FSK) in generalized K–...

Deconvolving heterogeneous tumour samples to identify constituent cell populations with differing copy number profiles using whole genome sequencing data is a challenging problem. Copy number calling algorithms have differential detection rates for different sizes and classes of copy number alterations. This paper describes how uncertainty in classification and differential detection rates can ...

The Negative Selection Algorithm (NSA) is a kind of anomaly detection method inspired by the biological self/nonself discrimination principles. In this paper, we propose two new schemes for the detectors re-editing and censoring in the NSA. The detectors that fail to pass the negative selection phase are re-edited and updated to become qualified using the Differential Evolution (DE) method. In ...

This paper introduces the concept of equivalent channel for mutual information performance analysis of multiplesymbol differential MPSK (M -phase shift keying) over timecorrelated, time-varying flat-fading communication channels. It is proven that differential detection scheme theoretically preserves the channel information capacity when the observation interval approaches infinity. A state spa...

the combination of graphene (gr) and nickel oxide nanoparticles (nio nps) yields nanostructured electrochemical sensor formed a novel kind of structurally uniform and electrocatalytic activity material. in cyclic voltammetry (cv) studies, in the presence of ep, nio/gr composite modified electrode shows a significantly higher current response for ep oxidation. based on differential pulse voltamm...

K`4 are for several reasons an especially interesting decay channel of K mesons: K`4 decays allow an accurate measurement of a combination of S -wave ππ scattering lengths, one form factor of the decay is connected to the chiral anomaly and the decay is the best source for the determination of some low energy constants of ChPT. We present a dispersive approach to K`4 decays, which takes rescatt...
