This paper introduces an iterative method to estimate the cointegrating vectors in the error correction models. The method provides the asymptotically efficient estimators for the cointegrating vectors if iterated once or more. If it is iterated until convergence, we may obtain the maximum likelihood estimator by Johansen. For all values of 1 ≤ k ≤ ∞, the k-step iterative estimators are asympto...

Turbo codes occupy a special place in the field of wireless communications for their outstanding performances in correcting errors that appear on transmission channels. This paper analyzes the influence of trellis termination methods on turbo codes performances, over a channel affected by impulsive noise and Binary Phase-Shift Keying modulation. The statistical model used for the impulsive nois...

The performance of the adaptive projection receiver (PR), a recently proposed joint detector for CDMA with error control coding, is investigated. It is shown that the adaptive version of the PR performs better than the algebraic PR. A close approximation of the error probability for the adaptive PR is derived. The performance improvement of the adaptive PR, which is of the order of 1-2dB in Eb=...

~ S ocially responsible investing (SRI) is moving into the mainstream of institutional investment management, but not uniformly and not without doubt. A 2004 Mercer survey reveals that 89% of investment managers in Asia and 69% of investment managers in Europe believe that SRI would be in the investment mainstream in the coming ten years, but only 36% of investment managers in the U.S. share th...

One of the ASR applications is the generation of transcripts to facilitate searching through multi-media collections containing spoken data. Especially in the broadcast news domain ASR systems have been successfully deployed to index large collections of news. First of all because retrieval performed on ASR generated transcripts with an word-error rate (WER) under 50% gives resonable results [1...

Conventional time-delay estimators exhibit dramatic performance degradations in the presence of multipath signals. This limits their application in reverberant enclosures, particularly when the signal of interest is speech and it may not possible to estimate and compensate for channel e ects prior to time-delay estimation. This paper details an alternative approach which reformulates the proble...

the objective in this study was to assess the performance of the control algorithms and determine the appropriate controller for aghili irrigation network. to evaluate the efficiency of the control algorithms, the performance criteria of the maximum absolute error, integral absolute error and steady state error were considered during the simulations of a one month period and with regard to the ...

High precision 3D LiDARs are still expensive and hard to acquire. This paper presents the characteristics of RSLiDAR, a model of low-cost LiDAR with sufficient supplies, in comparison with VLP-16. The paper also provides a set of evaluations to analyze the characterizations and performances of LiDARs sensors. This work analyzes multiple properties, such as drift effects, distance effects, color...
