There is a huge demand of video based services over internet and wireless networks, however, transmission of coded video bitstream over wireless channel is very challenging task. Various schemes have been proposed in the literature to combat the effect of transmission errors. In this paper joint source channel coding (JSCC) scheme is utilized to transmit the SPIHT (set partitioning in hierarchi...

This paper addresses the use of multirate filter banks in the context of error-correction coding. An in-depth study of these filter banks is presented, motivated by earlier results and applications based on the filter bank representation of Reed-Solomon (RS) codes, such as Soft-In Soft-Out RS-decoding or RS-OFDM. The specific structure of the filter banks (critical subsampling) is an important ...

Abstract The study aimed at investigating the efficacy of written corrective feedback (CF) in improving Iranian EFL learners’ grammatical accuracy. It compared the effects of focused and unfocused written CF on the learners’ grammatical accuracy. 75 EFL students formed a one control and two experimental groups. The focused feedback group was provided with error correction in tenses. The unfocus...

In this paper, we first study the error correction and detection capability of codes for a general transmission system inspired by network error correction. For a given weight measure on the error vectors, we define a corresponding minimum weight decoder. Then we obtain a complete characterization of the capability of a code for 1) error correction; 2) error detection; and 3) joint error correc...

A small macroeconomic model is constructed starting from a German money demand relation for M3 based on quarterly, seasonally unadjusted data for the period from 1976 to 1996. In contrast to previous studies we build a vector error correction model for M3, GNP, an innation rate and an interest rate spread variable to represent opportunity costs of holding money. Furthermore, import price innati...

Error correction technology, with which the errors that occur during transmission are corrected, is essential when high-quality digital video and audio are to be provided in digital broadcasting The principle of error correction is that the improvement in the reliability of the received information as a result of error correction will more than compensate for the increase in data caused by the ...
