Interleaved Forward Error Correcting (fec) Codes Based on Binar Shuffle Algorithm (b.s.a)
نویسنده
چکیده
Forward Error Correcting (FEC) is one of the technique is used for controlling errors without sending any retransmission to sender. Example of forward error correcting codes are hamming, lower-density parity-check (LDPC), tail-biting convolutional, turbo codes. Many wireless systems such as worldwide interoperability for microwave access (WiMAX), long term evolution (LTE) and enhanced data rates for the GSM evolution (EDGE) use forward correcting codes to sending messages. The main aim of this project is send the message from source to destination correctly (without losing any packets) and Manuscript received July, 2012 Phani Deep Challa, M.Tech CSE 2’nd Year Student, (Computer Sciencce and Engineering),J.N.T.U Kakinada/ Gayatri Vidya Parishad Engineering College, Vijayawada, India,+918500263931.

Here Binar Shuffle Algorithm is used to shuffle data in the interleaving process then burst errors are convert into random errors. The decoder detect and correct the errors very easy by using Belief Propagation (BP) Algorithm. Than performance also very high compared to with-out using interleaving Algorithms.
