Повний текст джерелаHow to rise the reliability of the data transmission is one of the main problem faced by modern digital communication designers. This paper studies the error-correcting codes being suitable for the channel existing both the random and burst error. A new error control scheme is given. The scheme is a concatenated coding system using an interleaved Reed-Solomon code with symbols over GF (24) as the outer code and a Viterbi-decoded convolutional code as the inner code. As a result of the computer simulation, it is proved that the concatenated coding system has a output at a very low bit error rate (BER)and can correct a lot of compound error patterns. It is suitable for the serious disturb channel existing both the random and burst error. This scheme will be adopted for a remote control system.

Повний текст джерелаWe consider optimal estimation of finite population parameters with data obtained via simple random samples. In this context, we extend a finite population mixed model proposed by Stanek, Singer & Lencina (2004, Journal of Statistical Planning and Inference) by including measurement errors (endogenous or exogenous) and auxiliary information. Assuming that variance components are known, we show that the proposed estimators/predictors have the smallest mean squared error in the class of unbiased estimators. Using simulation studies, we compare the performance of the empirical estimators/predictors obtained by replacing variance components with estimates with the performance of a traditional estimator. We also extend the finite population mixed model to data obtained via pretest-posttest designs. Through simulation studies, we compare the performance of the empirical estimator of the difference in gain between groups with the performance of the usual repeated measures estimator and with the performance of the usual analysis of covariance estimator obtained via ordinary least squares. The empirical estimator has smaller mean squared error and bias than the alternative estimators under consideration. In general, we recommend the use of the proposed estimators/ predictors for either asymmetric response distributions or small samples.

Background: Slow information processing speed is a common deficit of patients with schizophrenia, severely affecting their functions of daily life. The Tablet-based Symbol Digit Modalities Test (T-SDMT) is a quick and easy-to use measure assessing processing speed in patients with psychosis. However, the practice effect and substantial random measurement error have limited the utility of the T-SDMT. The purposes of this study were to explore the effect of different measuring methods on reducing the T- SDMT’s practice effect and the random measurement error. Methods: The author proposed three kinds of measuring methods on three groups of patients, respectively. The first group was measured by repeated measurements for 2 formal tests, the second group was to increase practice time for three minutes and then taking one formal testing, and the last group was the combination of increased practice times for three minutes and taking repeated measurements for 2 formal tests. The author recruited 87 patients with chronic schizophrenia. These patients were randomly assigned to 3 groups mentioned above, repeated-measurements group, increasing- practice-time group, combination of repeated measurements and increasing practice time group. Three groups of patients received test and re-test testing. The test and retest were administered 2 weeks apart. Results: The results of this study found that the three methods had good test-retest consistency. The increasing-practice-time group had the highest test-retest consistency. The combination group could effectively reduce random measurement errors. However, practice effect existed in all three groups. The increasing-practice-time group and combination group could reduce the practice effects effectively than the repeated- measurements group. Conclusion: The combination of repeated measurements and increasing practice time can reduce the random measurement errors, which was better than the other 2 groups. However, the random measurement errors needed to be further decreased for clinical utility. In addition to the practice effect, the future studies should further increase practice time and the number of testing (e.g., 3 formal tests), in order to enhance the utility of the T-SDMT.

There are not many literatures discuss the statistical inference when the measurement error and random effect exist in the generalized linear model. The main reason is that the distribution after integrating the random effect is no longer a generalized linear model, hence the conventional conditional score or corrected score are difficult in application. This paper discussed the estimation method when measurement error and random effect coexist in the log-linear model, the estimation was done by an extended corrected QVF score. We compare the efficient of the methods of Naive, regression calibration and partially conditional score with the proposed method by simulation studies.
