An application of LDPC code for wireless coherent-light commutation in atmospheric channel

摘要：

　　Low Density Parity Check code is more and more taken seriously in high-speed transmission.In this article we represent a LDPC coder and decoder which based on IEEE802.16e and realize the coder and decoder with Virtex-5 FPGA.By using Matlab to make an off-line system simulation,we analyzed and compared the LDPC performance under the different length of code for LDPC coder then analyzed the influence of different iteration to the LDPC BER performance of decoder.
