| Summary: | 碩士 === 國立臺北科技大學 === 電子工程系 === 106 === ATSC 3.0 is a new generation of broadcasting standards proposed by the Advanced Television Systems Committee (ATSC) in the United States. In this standard, new technologies are adopted such as Non-Uniform Constellation (NUC) and Layered Division Multiplex (LDM). This is a technique that has not been applied by any other broadcasting systems.
In this paper, we used two kinds of estimation methods, the log-likelihood ratio (LLR) and the maximum log-likelihood ratio, then we combined those methods with three decoding algorithms for Low density parity check codes. The three decoding algorithms include Sum-Product Algorithm, Min-Sum product, and Preferred Sum-Product Algorithm, on the ATSC 3.0 system. And last we observed the performance differences generated by different estimation methods and different decoding algorithms in different channel environments.
