Implementation Aspects in Simulation Extrapolation-Based Stocking–Lord Linking by Alexander Robitzsch

“…However, the original SIMEX approach can be computationally complex. This article evaluates two computational shortcuts to SIMEX-based SL linking through a simulation study: a quasi-Monte Carlo method that replicates items and a proposal using an approximate noniterative estimation instead of the iterative one in the SIMEX application of SL linking. …”

Turbo iterative acquisition algorithm for satellite high-mobility DSSS signal by Chunxiao JIANG, Jiawei WANG

“…To solve the problems of the low acquisition probability and high computational complexity in satellite high-mobility communications, a new factor graph was designed for acquisition of the high-mobility direct sequence spread spectrum (DSSS) signal, where time-varying Doppler rates were modeled by the random walk model.Based on the proposed factor graph, the turbo iterative DSSS signal acquisition algorithm was proposed.In the Doppler-estimation loop, the negative influence of Doppler frequency offsets and Doppler rates could be eliminated effectively.Then in the code-detection loop, constraints of each chip was used to recover the received signal, to achieve DSSS signal acquisition.Simulation results show that the proposed algorithm is capable of improving the acquisition performance at less 1.3 dB with low computational complexity.…”

On the sensitivity of feature ranked lists for large-scale biological data by Danuta Gaweł, Krzysztof Fujarewicz

“…The problem of feature selection for large-scale genomic data, for example from DNA microarray experiments, is one of the fundamental and well-investigated problems in modern computational biology.From the computational point of view, a selected gene list should be characterized by good predictive power and should be understood and well explained from the biological point of view.Recently, another feature of selected gene lists is increasingly investigated, namely their stability which measures how the content and/or the gene order change when the data are perturbed.In this paper we propose a new approach to analysis of gene list stability, termed the sensitivity index, that does not require any data perturbationand allows the gene list that is most reliable in a biological sense to be chosen.…”

Single-channel blind separation of co-frequency modulated signals based on Gibbs sampler by Yong YANG, Dong-ling ZHANG, Hua PENG, Shi-long TU

“…A Gibbs-sampler-based separation algorithm was proposed for single-channel co-frequency digital-modulated signals，which were received in non-cooperative ways.The probability density samples of unknown symbol sequences can be obtained by statistic method，and the computation complexity was not growing exponentially with the increase of channel order.With special emphasis on the separation algorithms of single pair of symbols，multiple pair of symbols and the tracking of channel responses.Moreover，the separation performance between Gibbs sampler and per-survivor processing(PSP) algorithm were analyzed and compared in detail.Simulation results show that，compared with PSP algorithm with L=4 for two co-frequency QPSK-modulated signals，Gibbs sampler can be nearly 17 times lower in computation complexity when the approximately performance is obtained.…”

Low complexity radar signal classification based on spectrum shape by Liang YIN, Rui LIN, Xiaolei WANG, Yuliang YAO, Lin ZHOU, Yuan HE

“…In order to solve the problems of high computational complexity, low recognition accuracy of low signal to noise ratio (SNR) environment and low fidelity of simulation data in radar signal modulation recognition, a low complexity radar signal classification algorithm based on spectrum shape was proposed.Signal spectrum was normalized, feature parameters were extracted by spectrum sampling method, and then machine learning classification model was trained.The test results of the data generated by the radar signal source show that the classification accuracy of Barker code, Frank code, LFM code, BPSK, QPSK modulation and conventional radar signals is more than 90% (SNR≥3 dB).The algorithm has low computational complexity, can adapt to the change of signal parameters, and has good generalization.…”
