| Summary: | 碩士 === 中原大學 === 通訊工程碩士學位學程 === 106 === This paper integrates error correction code and image restoration technology image transmission system by previous research to enhance the system''s ability to resist interference. And in the image transmission system by adding recursive decoding technology to improve the system''s performance. The main structure is to convert the decoding before and after the image processing code word comparison, the use of its difference to determine whether the basis for the wipe, wipe the completion of the remaining codeword back to the decoding Error-and-erasures decoding.
In recent years, since the low density parity check code can adjust the length of the codeword according to the system characteristics and have a better error correction capability to make it a popular research project. So we based on the previous system, proposed a video transmission system, the use of low-density parity-check code to replace the Reed-Solomon code, and based on low-density parity-check code plus five different image restoration results to do more , Also use the information combined with the channel and image repair information submitted to a recursive decoding architecture. Through the simulation results, the peak signal to noise ratio (PSNR) of the image is calculated to compare the system''s ability to resist interference.
