Application of Forward Error Correction and Polarization Scrambler in 160Gb/s High-speed Optical Communication System;

This paper presents an efficient packet loss recovery technique for voice over Internet based on parity-based piggy-backed forward error correction technique (PPFEC), which can recover most of the lossy packets during the lossy network.

The theory of the important technology of interleaver&deinterleaver used in the forward error correcting(FEC) for channel coding is introduced in this paper,and then one scheme of VHDL design and FPGA realization based on it and a practical method are put forward The method has the advantages of easy realization and less resource consume

The realization of the energy dispersal, FEC-coding, constellation mapping, symbol interleaving, 3780-point IFFT OFDM, synchro-PN insertion, SRRC-FIR filter, etc have been implemented based on FPGA.

FEC encoder design for the digital television terrestrial broadcasting system based on Chinese specification;

The reliability of data transmission in wirless communication system is improved using HARQ scheme with Automatic Repest Request(ARQ) and Forward Error Correction(FEC).

The FEC of channel codes can enhance reliability of messages-transforming without breaking real-time constraint of communication systems.

The objective is to decide optimal forward error correction(FEC) code rate to minimize the decoder distortion.
