FEC – Based Iterative transmission data through wireless network

IJEECC Front Page

Transform data from one wireless network to another in efficient manner.Perform number of operation directly on the transformed data with the controlled loss of accuracy. Turbo codes and Forward error correcting codes (FEC) scheme for data and overhead channels. Many efficient algorithms have been proposed for decoding these codes. Introduce a universal decoder to handle these two families of codes. TCP congestion control is implemented. The present work exploits the parity-check matrix (H) representation of tail biting convolutional and turbo codes. Enabling decoding via a unified belief propagation (BP) algorithm. BP algorithm provides a highly effective general methodology for devising low-complexity iterative decoding algorithms for all convolutional code classes as well as turbo codes. Performance analysis in terms of accuracy and memory footprint.
Keywords:Traffic analysis, iterative decoding, progressive transmission.
