چکیده

The classical Viterbi algorithm (ML sequence estimation) can be computed using a forward-backward structure, similar to that of the classical hidden Markov model forward-backward algorithm (MAP state estimation). This similarity is exploited to develop a hybrid algorithm which provides a mathematical connection between ML sequence estimation and MAP state estimation.

A Soft-Input Soft-Output Target Detection Algorithm for Passive Radar

Abstract: This paper proposes a novel scheme for multi-static passive radar processing, based on soft-input soft-output processing and Bayesian sparse estimation. In this scheme, each receiver estimates the probability of target presence based on its received signal and the prior information received from a central processor. The resulting posterior target probabilities are transmitted to the c...

Hybrid Maximum-likelihood Detector for Trellis Coded Spatial Modulation

Most spatial modulation (SM) schemes in the literature use hard-output maximumlikelihood (ML) antenna index detection. In trellis coded spatial modulation (TCSM) scheme, the detection should be also performed for the transmitted symbol, while the sequence decoding is performed using a hard-output Viterbi algorithm. We modified the hard-output ML-SM detector to determine a soft estimate of the t...

Application of Soft Computing Methods for the Estimation of Roadheader Performance from Schmidt Hammer Rebound Values

Estimation of roadheader performance is one of the main topics in determining the economics of underground excavation projects. The poor performance estimation of roadheader scan leads to costly contractual claims. In this paper, the application of soft computing methods for data analysis called adaptive neuro-fuzzy inference system- subtractive clustering method (ANFIS-SCM) and artificial  neu...

A HYBRID SUPPORT VECTOR REGRESSION WITH ANT COLONY OPTIMIZATION ALGORITHM IN ESTIMATION OF SAFETY FACTOR FOR CIRCULAR FAILURE SLOPE

Slope stability is one of the most complex and essential issues for civil and geotechnical engineers, mainly due to life and high economical losses resulting from these failures. In this paper, a new approach is presented for estimating the Safety Factor (SF) for circular failure slope using hybrid support vector regression (SVR) and Ant Colony Optimization (ACO). The ACO is combined with the S...
