Error correction by means of arithmetic codes: an application to resilient image transmission
نویسندگان
چکیده
In this paper, two novel maximum a posteriori (MAP) estimators for the decoding of arithmetic codes in the presence of transmission errors are presented. Trellis search techniques and a forbidden symbol are employed to obtain forward error correction. The proposed system is applied to lossless image compression and transmission across the BSC; the results are compared in terms of both performance and complexity with a traditional separated source and channel coding approach based on convolutional codes.

In this paper asymmetric price transmission mechanism and nonlinear adjustment between producer and retail prices of milk were examined in Zanjan Province of Iran. For this purpose, a Two-Regime Threshold Vector Error Correction Model (TVECM) and a Sup-LM Test developed by Hansen and Seo (2002) were employed for checking presence of a threshold effect. Application of unit root tests indicated...
متن کاملError Correcting Arithmetic Coding for Robust Video Compression
In this paper we present a novel error correcting arithmetic co/decoder, based on forbidden symbol detection and maximum a posteriori estimation. The error correction goal is obtained by means of a sub-optimal metric-first search technique that exhibits attractive performance in terms of error recovery and decoding complexity. The proposed technique is able to compress the input data and at the...
متن کاملError control by product codes in arithmetic units
Product (AN) codes constructed in weighted number systems are investigated with the aim of devising error control features suitable for application in arithmetic units. The previous theoretical framework, which was derived in the hypothesis of codes defined in a virtual range M = k A, is restated for any physical interval M = bn, where b is the radix of the system and n is the number of digits....
متن کاملA joint source and channel coding algorithm for error-resilient SPIHT-coded video bitstreams
We propose an analytical rate-distortion optimized joint source and channel coding algorithm for error-resilient scalable encoded video for lossy transmission. A video is encoded into multiple independent substreams to avoid error propagation and is assigned forward error correction (FEC) codes and source bits using Lagrange optimization. Our method separates video coding and packetization into...
